I'm not sure if you've ever read about the RNA world hypothesis, but you might find it interesting. Just today I was in the radio station, and kind of staring at the leather couch in our office. Somebody asked me what I was looking at and I went off on this soapbox about how incredible it is that I was looking at something that, in the end, is composed of atoms that don't represent the whole in the slightest, in terms of appearance. Then I went off about how everything is composed of atoms that are composed of mostly empty space and how incredible that is. Sometimes I think, and this is an absolutely insane thought that comes up a lot, but that life could be some sort of a dream. That what we are experiencing, what we feel, our trials and tribulations are in the end some sort of a simulation or a weird state born out of some cosmetic sentience. I first encountered that idea from Final Fantasy X, of all places, but it's something that I think about every so often. Life is impossible.It's pretty amazing that a few free floating amino acids developed into what we see around us every day.
