I'm an agnostic on this one. However, I still often silently disaporove of those who rationalize their opinions based on statistics and chances. We know nothing, really, about of those! Hard to sample something out of a single example. So in reality we know nothing about of those, such as the likehood of abiogenesis, of said life becoming multicellular, of surviving every geocatastrophe, of finally giving rise to an intelligent species, and if intelligent social, and if social technological, and if technological, surviving over deep time.
Please do consider. The milky way and it's planets are nowadays what Mars and Venus were in the beginning of the 20th century, the Atlantic Ocean for the first colonial explorers, Africa and China for the average middle ages man, and the dark woods a day's walk for the little children of the same man. Our subconcious seem to always place something out of the ordinary just beyond reach. It could very well be, and perhaps it's even likely, that one day, after we have sampled billions of stars, we reasonably assume there is one civilization per galaxy, or something along these lines.
