i have only been here for 20 and i have parents so i am guessing over 40 years

The earth (and its chemical reactions) wasn't born until about 8 billion years after the Big Bang ... things had slowed down a bit by then.

In genesis it said god made the earth in 6 days.  the hebrew word used for days is used also for a period of time, so you can conclude that god took longer than 6 literal days to create the earth. Who's to say we aren't still in the "seventh day" of gods rest from creating.  And dinosaurs and humans did co exist, a scientist in south america.  has found stones that have ancient depictions of triceratops and \nt-rex from 1000's of years ago.

SOMEONE SAID GOD CREATED EARTH IN 6 DAYS, WELL IT REALLY TOOK HIM 7, IF U R INTERESTED ON THAT READ THE 1ST CHAPTER OF GENESIS, I RECOMMEND THE "NEW INTERNATIONAL VERSION"(NIV)\nIT'S EASSIER TO UNDERSTAND.

you already answered your own question.  not as long as religious zealots roam the Earth!!

The earth as it was 100 million years ago.\n\nSimple really!

#        The earth is 6,000 years old position. The date 4004 B.C. is found in the marginal notes (Genesis one) of many King James Versions. This date was first placed in the King James Version by James Ussher in 1701. He arrived at this date by adding the lengths of the lives of the patriarchs as given in Genesis 5 and 11. In reality, this dating method is not infallible for a number of possible reasons. As far as the Bible is concerned, we can not date the earth with accuracy. It must be remembered that Genesis presents the earth as being created mature or aged (Gen. 1: 20 ff.).  \n\n#     The earth is 4.7 billions years old view. Scientists have employed a number of methods in trying to arrive at the age of the earth. The rate of erosion, rate of salt accumulation in the ocean, and the rate of decay of certain elements such as uranium, thorium, potassium, and rubidium. All of these methods including the "ore method," "meteorite method," and the dating of fossil remains are unreliable and contain many attendant variables.\n\n#     There are a growing number of scientists who are concluding the earth is actually relatively young. They have studied population growth, the amount of meteoric dust on the earth's surface, the quantity of nickel in the oceans, and carbon-14 build up. Many of these scientists believe the earth is more in the range of 7, 000 years old. "Beloved, one thing we do know is life begets life and creation implies a Creator: "In the beginning God created the heaven and the earth" (Gen. 1: 1). In all honesty, there are matters scientists and theologians do not definitively know as to the age of the earth. True science and the Bible, though, do not conflict.

The generally accepted age for the Earth and the rest of the solar system is about 4.55 billion years. I am not an expert on this matter, but I believe in science. If someday people find new convincing theories, I will be very open to accept them. But only 6000 years old? Come on, I don't buy it.

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.

Demographers have come up with estimates ranging between 69 billion and 110 billion humans.\n\n\nA complication, among scientists at least, is that we do not know precisely when our primate ancestors became human. Many researchers have arbitrarily settled on one million years ago, even though our own subset of the genus Homo, H. sapiens sapiens, did not emerge until around 40,000 years ago.\n\nIf the paleolithic crowd (1 million years to 25,000 years ago) strikes you as too crude for admission to the communion of saints, subtract 36 billion or so from the figures above.

How Old Is The Earth, And How Do We Know?\n he generally accepted age for the Earth and the rest of the solar system is about 4.55 billion years (plus or minus about 1%). This value is derived from several different lines of evidence.

In the first place, god did not create the world in 7 days -- or any other period of time.  The universe is 13.7 billion years old; the earth is about 4.5 billion years old.

Earth is the third planet from the Sun. It is the largest of the solar system's terrestrial planets, and the only planetary body that modern science confirms as harboring life. Scientific evidence indicates that the planet formed around 4.57 billion (4.57×109) years ago, and shortly thereafter (4.533 billion years ago) acquired its single natural satellite, the Moon.

It's all guess work.\n\nTime did not exist until flesh man was created.\n\nConsider some scientific estimates or guesses. Not all scientists are going to agree. The Universe or heavens 20 billion years old. The Earth 4.6 billion years old. The Moon 200 to 300 million years younger than the Earth. Dinosaur extinction 65 million years ago. The Ice Age 2.5 million years ago. Oldest evidence of flesh man 7000 to 14000 years old.

The generally accepted age for the Earth and the rest of the solar system is about 4.55 billion years (plus or minus about 1%). This value is derived from several different lines of evidence.\n\nUnfortunately, the age cannot be computed directly from material that is solely from the Earth. There is evidence that energy from the Earth's accumulation caused the surface to be molten. Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface.\n\nThe oldest rocks which have been found so far (on the Earth) date to about 3.8 to 3.9 billion years ago (by several radiometric dating methods). Some of these rocks are sedimentary, and include minerals which are themselves as old as 4.1 to 4.2 billion years. Rocks of this age are relatively rare, however rocks that are at least 3.5 billion years in age have been found on North America, Greenland, Australia, Africa, and Asia.\n\nWhile these values do not compute an age for the Earth, they do establish a lower limit (the Earth must be at least as old as any formation on it). This lower limit is at least concordant with the independently derived figure of 4.55 billion years for the Earth's actual age.

The official estimate now is 13.7 plus or minus 0.2 billion years old.\n\nBut this continues to be a tricky number to pin down. It depends primarily on the rate of expansion of the universe. Recently it has been found that the rate of expansion is increasing (that is the universe is expanding more today than it it did a billion years ago, and will be expanding faster a billion years into the future).\n\nHaving said that this continuing field of study in cosmology is no consolation for Young Earth Creationists. I mention that because some have a habit of jumping on any disagreement in science as a way to promote their own. The universe is clearly between 10 and 20 or 25 billion years old. Not 6,000 years old.
