evolution is not predicated on knowing how, where and when the game of life kicked off (maybe the 'big ref' was there to blow the whistle who knows), but it just happens to perfectly explains the diversity of life on earth alive now and from the fosill records going back hundreds of million of years. Sadly for now, its a bit tough to do research on what actually happened 4 billion years ago. Scientists will get there I have the faith, man.
