Nature of God or Gods?

What do people think about the nature of God or Gods? Can other Gods exist?

In someway's I think they do, or at least once enough people start believing in one they become nigh on impossible to disprove (at least to the believers) assuming they haven't been assigned any clearly impossible actions or attributes.
As if enough people believe there belief will start to influence others actions, in a manner similar to how Christ's teaching affected us, and once enough people are effected it starts to affect the culture.

Also I think when people start to believe and enough in a certain culture do then statistically improbable effects will start to be taken as miracles. People who pray will start to think their prayers are answered as they them selves think up ways of solving problems they were praying about or something happens that fits what they were praying for.

You see it a bit in the Christian church, "all glory to God", and the believe that anything that happens somewhat easier than expect or things that don't work out are due to the will of God. If something goes right well then it was clearly God's will and if something doesn't happen then it was also Gods will.

The problem here I think is that people seeking prove of the existence of God simply start to assign the thanks or blame to anything that happens to God. This also allows them to avoid having to feel as much responsibility if things go wrong I think.

This may just be the outpourings of an overly cynical mind but I hope not.
