FTR, looking at all the amazing things and going "wow....how is that even possible?!? Just - wow", while a universal human trait and the basis for so many belief systems, still does not constitute reason. It essentially boils down to "I don't understand, therefore god", or more correctly; appeal to ignorance. Kirbmarc has the right of it; chemical reactions occur because of the physical laws that govern the universe. Biology follows, as does sentience and civilization. Time and brownian motion dude. That's all.
Doesn't stop the universe from being gape-jawed wonderful.
