Are we made up out of the same atoms that were around when the earth was first made?

Yes.  There is a very small amount of matter that enters the atmosphere from space (meteorites), but essentially it is all just being recycled. Some atoms of oxygen you breathe in may have been breathed by a dinosaur, or one of the pharoahs!

We are all related.  You will see scientists, who mainly believe in the big bang theory, will often describe us as "stardust".  The reason for this is that when planetary nebula are being created, and a star results, the leftover matter from the new star is what planets condense from.  They are made of the same basic materials.  \n\nIn addition, every basic element on the periodic table from hydrogen to iron (including carbon; e.g. "carbon-based life forms" such as us) is naturally produced inside the sun, and every larger element can be produced from the same basic ingredients by other processes.  \n\nIt is no coincidence that we (and everything else) are made of the same elements as the rest of the solar system and much of the universe.

we are human beings made of complex carbon compounds which are made of basic particles molecules which are agin made of electrons and protons and nuetrons which are again made up of quarks..............we are livng in this universe with reason tha twe see the way it is.........its as per the basic anthropic principal............now as far as being existing in terms of pairs let me explain you...\nwe live in universe which is made of particles and antiparticles every particle has a corresponding antiparticle.  A particle and its antiparticle have identical mass and spin..now these both carry various as per earths scientist have designed such as electric charge, color charge, flavor, electron number, muon number, tau number, and baryon number. so if go into deep into this it will be difficult to understand..... so we exists in pairs...so check out man to see whether ur anti of yours.you will be annhilited man.....so better be careful...one another approch is the many world theory which states us that there are many parallel universes around they depend upon the every action do in present i guess.....its also called as catastrophe if you know.....\nso there u go that swhy we r not alone and only one....\nregarding the last two this called as world as our english dictionary given a name to this earth the other name....and if you dnt who you are then you better stop watchin movies like matrix..........and all that crap....hope u understand the answer.........live life bye.......

Earth is thought to be between 4.5 and 4.8 billion years old. The age of Earth is found by measuring the age of very old Earth rocks. This is done by measuring the rate at which elements of the radioactive metal uranium decay (break down) into lead. Scientists have also measured the age of meteorites which have fallen onto Earth's surface, and the age of moon rocks brought back by the Apollo astronauts. Both the meteorites and the moon formed around the same time as Earth, and they show similar ages.\n\nIf you want a break down of that timespan in terms of Geologic Periods, see:\nhttp://www.cotf.edu/ete/modules/msese/earthsysflr/geotime.html

As other posters have remarked, life is formed from non-living matter all the time. However, I think you are asking how the first life formed. But it's important to understand that the first life wasn't formed by "biological processes" - because there was no biology at that point. The processes were purely chemical.\n\nThe answer to how life formed, though, is: we don't really know, yet. However we do have some good ideas.\n\nOne of the above posters referred to an experiment - it's actually known as the Miller-Urey experiment. Miller discovered that he could generate small amounts of amino acids - which are the basic building blocks of life - by passing an electric current through a mix of gases which represented the composition of the atmosphere billions of years ago. \n\nNow, there's a big gap between these amino acids and the first cell, which is where creationists will try to mislead you by saying that a cell is too complex to have formed on its own. But, of course, no-one is saying  cell did form straight away. There's probably a gap of millions of years between the amino acids and the first cell .This is where the most active research is going on - scientists now think that before DNA formed, life depended on a simpler structure called RNA, so they refer to this period as the RNA world. It's a very interesting area of research.\n\nThe other way creationists try to mislead you is by dishonestly claiming that scientists believe in "spontaneous generation", which was disproved hundreds of years ago. In fact, one has nothing to do with the other - spontaneous generation was the idea that fully-grown creatures like mice spontaneously formed from piles of grain. Of course this idea isn't accepted by anyone today, and is a long way from the detailed ideas about the formation of amino acids and cells that scientists are really working on.

Check out the source below, there are great animations there as well as the following information:\n\nThe origin of the Earth\nThe age of the Earth was once, and still is, a matter great debate. In 1650 Archbishop Ussher used the Bible to calculate that the Earth was created in 4004BC. Later on in the mid-nineteenth century Charles Darwin believed that the Earth must be extremely old because he recognised that natural selection and evolution required vast amounts of time. \n\nIt wasn't until the discovery of radioactivity that scientists began to put a timescale on the history of the Earth. Rocks often contain heavy radioactive elements which decay over long periods of time, the decay is unaffected by the physical and chemical conditions and different elements decay at different rates (These rates are slow and half-lifes of several hundred million years are not uncommon)\n\nThroughout this century the race has been on to discover the oldest rocks in the world. The oldest volcanic rock found so far has been dated at 3.75 billion years old, but this is not the whole story. Meteorites created at the same time as the Earth hit us all the time, radioactive dating shows that they are about 4.55 billion years old.\n\nTHE EARLY ATMOSPHERE\n\nThe present composition of the atmosphere is: 21% OXYGEN \n 78% NITROGEN \n 0.04% CARBON DIOXIDE \n ~0.9% ARGON \n\nThe atmosphere wasn't like this when the Earth was created over 4½ billion years ago.\n\nTHE FIRST BILLION YEARS\n\nThe Earth's surface was originally molten, as it cooled the volcanoes belched out massive amounts of CARBON DIOXIDE, STEAM, AMMONIA and METHANE. There was NO OXYGEN. The STEAM condensed to form water which then produced shallow seas. \n\nEvidence points to bacteria flourishing  3.8 billion years ago so this means that life got under way about 700 million years after the Earth was created. Such early forms of life existed in the shallow oceans close to thermal vents, these vents were a source of heat and minerals. \n\nTHE NEXT BILLION YEARS\n\nThese primitive life forms then took the next evolutionary step and started to PHOTOSYNTHESISE (using sunlight to convert carbon dioxide and water to food energy and oxygen). This was an important turning point in Earth history because the carbon dioxide in the atmosphere was being converted to oxygen. \n\nThese green plants went on producing oxygen (and removing the CO2).  \nMost of the carbon from the carbon dioxide in the air became locked up in sedimentary rocks as carbonates and fossil fuels. Carbon dioxide also dissolved into the oceans. \nThe ammonia and methane in the atmosphere reacted with the oxygen.  \nNitrogen gas was released, partly from the reaction between ammonia and oxygen, but mainly from living organisms such as denitrifying bacteria. (remember that nitrogen is a very unreactive gas and it has built up slowly).  \n\nTHE LAST 2½ BILLION YEARS OR SO\n\nAs soon as the oxygen was produced by photosynthesis it was taken out again by reacting with other elements (such as iron).This continued until about 2.1 billion years ago when the concentration of oxygen increased markedly. As oxygen levels built up and then . . . . . . \n\nThe ozone layer was formed which started to filter out harmful ultraviolet rays. This allowed the evolution of new living organisms in the shallow seas.

The Earth is 4,570,000,000 years old, approximately; though many Creationists think it to be only 6000 "without proof otherwise" they are wrong: we have proven it using gravitational measurements of other planets, measurements of solar brightness over time, radioactive dating, continental drift, and many other factors. If you want to  force religion on people, don't do it in a SCIENCE forum! You will only cause heated debates and great offense from both sides.

The matter that made up the sun and planets existed at one time as a very large disk. As the matter clumped together, it was already on the same plane. That's the theory, anyway.

What is the Earth made of?\nhttp://www.leo.lehigh.edu/envirosci/geology/penngeo/whatis/whatis.html\n\nChemical Structure of the Earth\nhttp://www.earth.northwestern.edu/people/seth/202/lectures/Minerals/compintro.htm\n\nStructure and composition of the Earth\nhttp://www.amonline.net.au/geoscience/earth/structure.htm\n\nThe way we know what makes the earth, chemically speaking is to test for it.  Such as the composition of the atmosphere is put through a mass spectrometer (http://answers.yahoo.com/question/index?qid=20060905084043AAQ20dx) this tells scientist exactly what elements are in the test sample and in what percent!  We do the same for tests in the earth, of course there are abundant other tests to perform, both chemical and by hand, to tell us a more rounded story of the formation of the earth's history.

At the bottom of the perodic table...\n\nThey are technetium (at. no. 43), which was the first element to be synthesized, promethium (at. no. 61), astatine (at. no. 85), francium (at. no. 87), and the transuranium elements (at. no. 93 and beyond in the periodic table). Some of these elements have since been shown to exist in minute amounts in nature, usually as short-lived members of natural radioactive decay series (see radioactivity).\n\nThe synthetic elements through at. no. 100 (fermium) are created by bombarding a heavy element, such as uranium or plutonium, with neutrons or alpha particles. The synthesis of the transfermium elements (elements with at. no. 101 or greater) is accomplished by the fusion of the nuclei of two lighter elements. Elements 101 through 106 were first produced by fusing the nuclei of slightly lighter elements, such as californium, with those of light elements, such as carbon. Elements 107 through 112 were first produced by fusing the nuclei of medium-weight elements, such as bismuth or lead, with those of other medium-weight elements, such as iron, nickel, or zinc. Element 114 was first produced by fusing the nuclei of plutonium and calcium and subsequently by fusing the nuclei of lead and krypton, as was element 116. Element 115 was produced by bombarding americium with calcium, and element 113 resulted from the radioactive decay of element 115. The claim by Lawrence Berkeley National Laboratory to have created element 118 has been retracted.)\n\nThe transfermium elements are produced in very small quantities (one atom at a time), and identification is therefore very difficult because of half-lives ranging from minutes to milliseconds and the need to identify the products by methods other than known chemical separations. This has led to controversy over reported discoveries and over the naming of the elements. It has been predicted that one isotope of element 114—containing 114 protons and 184 neutrons—would be very stable because its nucleus would have a full complement of protons and neutrons. Termed an “island of stability,” its half-life might be measured in years. However, none of the three isotopes of element 114 synthesized as yet have as many as 184 neutrons, and their half-lives are still in the millisecond range.

For the past 50 years, scientists have attacked the question of how life began in a pincer movement. Some approach it from the present, moving backward in time from life today to its simpler ancestors. Others march forward from the formation of Earth 4.55 billion years ago, exploring how lifeless chemicals might have become organized into living matter.\n\nWorking backward, paleontologists have found fossils of microbes dating back at least 3.4 billion years. Chemical analysis of even older rocks suggests that photosynthetic organisms were already well established on Earth by 3.7 billion years ago. Researchers suspect that the organisms that left these traces shared the same basic traits found in all life today. All free-living organisms encode genetic information in DNA and catalyze chemical reactions using proteins. Because DNA and proteins depend so intimately on each other for their survival, it's hard to imagine one of them having evolved first. But it's just as implausible for them to have emerged simultaneously out of a prebiotic soup.\n\nExperiments now suggest that earlier forms of life could have been based on a third kind of molecule found in today's organisms: RNA. Once considered nothing more than a cellular courier, RNA turns out to be astonishingly versatile, not only encoding genetic information but also acting like a protein. Some RNA molecules switch genes on and off, for example, whereas others bind to proteins and other molecules. Laboratory experiments suggest that RNA could have replicated itself and carried out the other functions required to keep a primitive cell alive.\n\nOnly after life passed through this "RNA world," many scientists now agree, did it take on a more familiar cast. Proteins are thousands of times more efficient as a catalyst than RNA is, and so once they emerged they would have been favored by natural selection. Likewise, genetic information can be replicated from DNA with far fewer errors than it can from RNA.\n\nOther scientists have focused their efforts on figuring out how the lifeless chemistry of a prebiotic Earth could have given rise to an RNA world. In 1953, working at the University of Chicago, Stanley Miller and Harold Urey demonstrated that experiments could shed light on this question. They ran an electric current through a mix of ammonia, methane, and other gases believed at the time to have been present on early Earth. They found that they could produce amino acids and other important building blocks of life.

We, along with everything else in the world, are made up of atoms. Atoms are the basic building block of all matter.  The periodic table lists the different "elements" in the universe. Each element is made of a unique kind of atom, and there are no other kinds. For example, you can have oxygen atoms, or carbon atoms, but there are no plastic atoms. Anything more complex than the elements is made by sticking atoms together to form molecules - you *can* have a plastic molecule.\n\nAtoms consist of a nucleus, which contains protons (positively charged particles) and neutrons (no electrical charge.) The protons and neutrons are the heavy part of an atom. Electrons (negatively charged particles) orbit around the nucleus. \n\nThere are always the same number of protons and electrons, so the positive and negative charge cancel each other out. The number of neutrons can vary. Adding the number of protons and neutrons will give you the "atomic mass" of an element.

I doubt we know it yet.  We know of a limited number of stable atoms that can be found in our solar system, and a few that have been made by man, though many of the nam made ones are not stable.  Most of the heavier atoms were created during several Supernova explosions.  It is reasonable to suspect that a planet system that formed from the debris left from extremely massive Supernova, the energy from those explosions may have created some exotic element we are not even aware of yet.  Perhaps such element exist on Earth, but in such tiny amounts that we are not even aware they are there yet.

our earth is about 4.5 billion years old.\nwell its a mystery that whether all the planets have been created atonce,but\naccording to the big bang theory there was a large explosion resulting in te formation of planets.\nnoone can say this is true or not..

NONE.  All things were created!  Things adapt to changing environments, but they never turn into something entirely new.

This is a good question...it's actually something I've thought about before. It seems snobbish to believe that we are the only living things in the infinite universe, yet the Bible does not describe creation of anything but the Earth and its beings. \n\n"In the beginning, God created the heavens and the earth." Genesis 1:1 \n\nThis verse states that the heavens were also created by God. Although the heavens are mentioned, the Bible may not go into detail about them for the simple reason that they were unknown at that time. For all we know, God could have created an identical planet to ours that we know nothing about. But in the past and present, it has been impossible to find out about anything much beyond our solar system.\n\nAs for the question of 6,000 years ago...well, it is pretty much a proven fact that time was measured differently when the Bible was written. People were recorded to live into their nine hundreds. So some of the "heavens" could have been created much before the earth and simply recorded as a day.\n\nThis is my theory...I hope I helped.

Excluding any matter leaving the Earth (satellites) and entering the Earth (meteors), yes.  We are all the by-product of millions of years of evolution and environmental recycling, and could very well be sharing atoms with ancestral monkeys.
