If bacteria was the first life form on earth where did it come from?

Answer 1

Bacteria was not the first "life" form on Earth. Bacteria are descendant from simpler life that did not have the complexity of bacteria. That "life" evolved from a self replicating organic molecule that was made up from common amino acids and proteins. These first "life" forms were even simpler than viruses. Those self replicating molecules come about when you mix large quantities of amino acids, hydrocarbons, proteins, water, and heat (all of which were common and result from natural processes) with enough time (roughly 100 million years once the oceans began to form on the early Earth). Life is the natural consequence of carbon based chemistry. The problem most people have with understanding the process is that they really don't follow all the evidence all the way to the true conclusions. They stop because its "Too hard to learn all that organic chemistry." or it conflicts with preconceived ideas.

Answer 2

As a scientific document, the Book of Genesis was debunked right about the time that humans started using the scientific method to investigate nature, so the short answer is no, Genesis was already debunked long before this idea was proposed. On the other hand, for those who choose to read Genesis as a proposed description of natural origin that people were able to formulate from history and tradition, there is no debunking needed, nor is any possible. It stands as a best effort in the pre-scientific world. For others still, the writings in Genesis hold meanings both more subtle and more profound than a scientific explanation. They describe things about people that science would only approach after the theories of natural-selection, anthropology, psychology, neuroscience, and economics were adequately developed to begin to address such issues. So once again, the answer is no.

Answer 3

Mato has just given you as good an answer as you could get in 200 words or less. Bacteria are highly evolved compared to the first humble molecular self-replicators in their lipid bubbles. Brenda, the world is not as simple as the first two pages of Genesis. One has to do some serious reading in order to understand these things.

Answer 4

bacteria life form earth

Answer 5

Believers would say it came from god, atheist says it evolved from simpler live, and that simpler life also came from a more simpler life and here we go into and endless loop. so as you see the evolution maybe came out with reasonable explanations to some areas but failed to tell a beginning to the story

Answer 6

many scientists theorize that an asteroid of some kind that may have had simple organisms on it may have collided with earth. after that, the bacteria would have evolved

Answer 7

I saw a video in science class once and it said that there was a theory that there were cells and in nature cells have to split, cell splitting is inevitable, so thats why more advanced life forms started

Answer 8

Evolution does not explain the first life forms or the creation of the universe. There is a need for a creator and an intelligent design at least at the molecular level.

Answer 9

You are asking the age old question that there will never be an answer to. Why are we here? No way of finding that one out. Because as humans we believe that something has to start from something, therefore that question will forever be impossible to ask. If god is true, which I hope he is, hopefully we will find out when we die.

Answer 10

If there is proof that bateria was created before humans =I would be pleased to know.
