Humans are made of the same stuff as stars but with some such complexity as to mysterously appear alive. Why?

Gold and helium are made of the same stuff, but are radically different.\n\nWhat is important is how the compenents are arraigned.  And by that, I mean through natural processes.\n\nYes, we are made of star stuff.  Without iron created in a supernova somewhere, our blood wouldn't work.\n\nHumans didn't "mysterously" appear.  From the first organism to humans a few billion year laters, it took trillions of babysteps and trial and error to build the eventually more complex organism of man.\n\nThe alive question is simple to.  A computer in pieces doesn't do a darn thing, but if you put it together correctly, it operates perfectly in an extremely complex manner.  At some point, humans emerged into consciousness when all the pieces, via natural selection, fit together in the right way.

There have been a lot of questions about this recently, and as you stated, there are billions of galaxies out there.\nHow many we don't know.  But certainly enough that it isn't out of the question that a lifeform could evolve out there.  Not necessarily humanoid but a lifeform.  They may not look anything like humans or for that matter anything we got on earth.\nThe fact is, everything we know about living things is based on what we have available here on earth.\nThere is the possibility of a lifeform that doesn't require an oxygen based atmosphere.  \nWe are still in the infancy stage of development in space.  If the beings out there are advanced by say 10000 years and have the technology, they could already have been here and are monitoring us as we plod along.  Nobody knows for sure.\nAll we have are guesses and speculation.  No hard facts are available.

The mere thought that life ONLY exists on Earth and nowhere is ridiculous!!!! For every star you can see in the night sky, there is a distinct possibility for planets and intelligent life.....why else would they be there?

most things that scientists have made are duplicates of what God has already created but they have not be able to make LIFE. They cant make "real human" because the source of life is with God.

I think it stems from the fact that imperfect creatures, who were made in the likeness of another imperfect being, gaining the same knowledge of that imperfect being. Therefore, all of existence is flawed.

I think there is definitely other forms of life. Whether there human or not don't know. Since humans haven't been around nearly as long as the planets, stars, galaxies etc. I would bet that there are far more intelligent life forms out there.

I'm absolutely confident there is life out there.  But I hope they have better things to do than draw designs in crops and play peek-a-boo with airline pilots and nerds.\n\nAnd we only look like we do because of the way life developed on Earth.  There is no reason to believe that aliens would look anything at all like us.  Unless of course we came from the same place at some time thousands of years ago and we adapted to Earths enviroment, then of course we could be somewhat similar.

why not most people are stuff when they are alive anyway right?

It may be you are not sure how wonderous you are...I mean here you are, an entity made from elements that resulted from the explosions of stars...the formation of our earth and solar system...the accidents of evolution and history...and though it is extremely unlikely - you are here!  You are here to create and find your purpose...pretty amazing...when you think of all this you may start to think that other people's opinions are not so important...

We are humans, just another creature here on earth. We evolved from bacteria. But for some strange reason, some people think a fictional man in the sky put everyone here.

There are things that happen in this world that are above our understanding.  If we were to know how everything worked, we would be God.  Not understanding everything makes us human.

I think aliens exist, but I don't think they live among us. Think of Earth and all of the cosmic and environmental factors that are required to sustain and promote life.  I think it would be unusual for similar conditions to exist in other galaxies that will produce intelligent beings that look exactly like humans.

Though considered nonliving they have some characteristics of living beings. They are composed of either DNA or RNA which is a biology subject. Besides they reproduce (though in living host cells) and also mutate. Also because they cause diseases.

Have to realize, the body is made of of two sides, joined in the middle. They are not identical. Most people have seen pics of mirror images of the face.. one is unable to recognize that person.. So, it is not uncommon for those differences to be quite obvious.

people are made from bacteria..\nactually,a human being is a big bacteri..\nwhen a single celled bacteria was formed with another celled bacteria ithey will form a multi celled bacteria..\nwith these process,a human being is created..\nactually,a brain is made up of multi cellular bacteria..\n\nthere is also another theory that explains that we came from monkeys..\nanother one tells about adam and eve.. \nfrom the bible,it states there that god created men from his replica..\nI guess all of it are actually correct..\n\nwell,you just need to choose an answer..\nnobody really knows the truth..

Now, in your main question, you use the generic term "ones," but in the details you use "human beings."  It is possible we are the only human beings, since that refers to a specific pattern of physical and mental processes.  But the only Ones, as in living, conscious, self-aware beings?  That would be statistically amazing, given how many stars there are, and how many planets revolve around our star.  Science fiction has long estimated the number of habitable planets, the number which are in fact inhabited, etc.  I can't say how many, but I'd be truly amazed if we are the only ones.

Absolutely.  There's evidence that planets with attributes similar to Earth exist.  In fact, scientists recently sighted a planet in a star system close to us that seems very similar to Earth.  Now UFO's are a bit more dubious, but then humanity has only been around for 20.000 years (maybe 50,000, depending on who you believe), while the universe has been around for at least nine billion years, and maybe up to seventeen billion (though I think that's probably stretching it a bit).  I would say there's been more than ample time for more advanced lifeforms to appear in that timeframe.
