What is life scientifically?

It isn't that rocks got together and formed life. In early time there were lots of interesting chemicals and energy floating around. These got together and formed various complex molecules. Some of these evolved into life forms. Is this complex? Yes. Can a teenager understand it all and make sense of it? Likely not. I suggest reading and studying biology. Speciation is a fascinating subject. On the other hand if your a troll for Jebus then he must have caused it all as the book says so. After all no one would have written a fantasy novel that long ago and if lots of folks believe it it also must be true.
