Yes but if God doesn't exist (and for the record I'm just playing devils advocate, I do believe in God) then there is no reason for anything. The Universe didn't create itself for any reason. It just developed. There is no meaning to life or reason for existance. Mankind and animals and plants and single celled amoeba are just a product of biology which just happens to be a way that physics works, and that physics just happens to be the way things work. Nature doesn't care a bit what happens. It's not anti-climatic for the simple reason that there is no climax, the Universe is created by a physical event, it exists for a few billion years and then falls apart. We may well be the only life in the galaxy. Just because we, within the whole reach of existance, can think and recognise our own existance doesn't mean there must be other life forms. That said though, I think that the multiverse is so large probability would seem to show that if it happened here it can happen elsewhere. People talk of finding planets capable of producing life, but usually they are stuck only thinking of life as we know it....jim
. if there is a 1 in a billion chance of earth like life than there is another 1 in a billion chance for each of the other 999,999,999 possible forms of life perhaps. The end result of which may be that every planet in the multiverse has a form of life that developed and is natural for that planet.
