How did the chemicals for life come together??..

Not only can abiogenesis happen, and did happen, it may have happen more than once in the history of life on earth. It was once thought that all life on earth descent from a common, bacteria like Prokaryote ancestor. It is now recognized that what was once thought to be the one big related family of bacteria in fact consist of two different families- the archaea, and the prokaryote. Members of these two families look similar under microscope, but uses completely different biochemical processes for the most basic functions in such a way that cast doubt about whether the two families could have descended from one common functioning organism. Thus abiogenesis may have happened on earth at least twice.

I have to say, I find this idea fascinating. I have never believed in the idea that everything comes from a common ancestor. I wouldnt be surprised if there was more than two families.
