Just like we can't prove or disprove that there isn't an invisible flying silent all knowing dragon floating around. And even if we do believe that there does exist a God then we reach the problem of which God really exists.

The only reasonable solution to this conundrum is to study and think about ethics and exist with out causing any unnecessary suffering to anyone or anything. That way what ever God that may exist that is worthy of worship will be content and so will your fellow human beings. To hell with dogmatic beliefs and fairy tales that have only led people to conflict.
