Religious folk believe that God created the universe. Fine. Those of you who are atheists, therefore, must surely believe the possibility that there are (or have been) lots of universes?
My thinking is this - we know a universe can come into being from, essentially, nothing. Because we're in one. And within that universe there is never just one of something. There are at least 2,500 species of moth in the UK alone, for example.
So it seems unlikely that only one universe would have developed. If it can happen as easily as it seems to have - and with no outside influence as you atheists believe - then it should have happened countless times? And presumably evolution would have happened in a similar way in all of these times?
I know the multi-verse theory isn't particularly new, but would you agree that if you don't believe God created one universe then it's highly like there are many, many universes (we just can't see/get to them because we're in this one)? When compared to all other events that are able to happen due to the laws of nature/physics etc. it's surely very very unlikely a universe would only come about just one time ever?
