Scientists have pretty strong evidence to suggest that, during the formation of the Earth, conditions were ideal to form simple proteins, and for these proteins to bind to form DNA and single cell organisms (as far as I know, they're been able to replicate the creation of proteins out of thin air). Single cell organisms, like amoeba, can live in the most extreme conditions and you'll commonly find them living near underwater volcanoes. Naturally, cells experience random mutations as genetic strains are corrupted or form differently. Sometimes this leads to a stronger life form, which survives. Speed this up a few million years and we're crawling out the water on our bellies. Speed it up a few more million and we're monkeys building huts.
