How Life Began

Overview

Was life triggered by some event, like lightning hitting a pond full of amino acids? Earth was teeming with life billions of years before the dinosaurs existed. Single celled organisms inundated the oceans, and the soil swarmed with living creatures. Where did it all come from and how do you go from a single-celled organism to a trillion-celled organism like man?
