Atheists: Obviously you don't believe in "God". Do you believe in other...?

I reject the idea of any supernatural phenomena. There might be aliens out there that are far more advanced then us. Who knows, there seems to be scant evidence on the subject. But, the universe is very big and we cannot rule out the possibility that abiogenesis occurred on another planet somewhere in the universe that has conditions favorable for life. After all, it happened here.
