The Origin of Life on Earth

You must have wondered about it before, haven't you? How did life begin on earth? I mean the very first thing. The first unicellular organism, billions of years ago. Is it even possible? As it happens, our understanding of chemistry, biochemistry, and biology has become so sophisticated over the years, that we now have a pretty reasonable grasp as to how abiogenesis must have occurred. This is the spontaneous generation of life from non-living material. As incredible as it sounds, there is a lot of science to discuss here, so let's get into it!
