How did life form on earth?

[Night Fury]

How did life (the earliest form of life) form on earth? What were the requirements? The chemicals need for it and the precise amount of heat energy etc. 

 

I'd highly appreciate anyone who answers this question. Thank you

Maybe a better question might be to ask who formed the earth and the environment so that the humans could occupy it in the beginning. If you are thinking of going back further than that, then maybe asking what or who had the consciences to understand and be able to form life in the beginning, even if that boils down to matter, atoms, fluids etc, who formed them and if the big bang enters the equation, who created and caused that ?

If somebody caused and created the big bang, were they inside the universe already, or outside of it? I suppose we would have to look the answers up in the holy bible. But I seem to have an outdated edition.

People are working on models and have possible working parts of the puzzle but nothing concrete as yet. You can search the internet for 'abiogenesis' if you want to have a look around for the models.

There are no definite answers to this. It is a huge area of research with many plausible hypotheses for many of the components and steps involved.

It would take an article, or even a book, to start answering this.

I think you should to google "abiogenesis" and then come back with more specific questions.

That would only be a sensible question if there was evidence that the Earth was formed by someone other than natural forces. (And, although there are some unknowns, we know a lot more about the big bang, the creation of stars and galaxies and, ultimately, the Earth than we do about the origin of life on Earth.)

You can start from looking at Urey-Miller experiment. They tried to experimentally mimic the prebiotic earth environment and how it can lead to formation of simple organic compounds such as amino acids.

For more details such as experimental conditions and chemicals you can try to find the book written by Alexander Oparin "The origin of life" where further details of the experiment and results are given.

But none of them are final theory, these are just experimental proofs which suggest some possible ways how life could have originated on earth.
