Does God Exist?

In the discussion about the cosmological arguement in proving God's existence one argument was that there can be an infinite series of reasons or causes for existence of a contingent. If this is true then there must be some sort of creator for God. This seems to disprove God as the one infinite creator of all things. It is likely that there is a sort of "infinite regress" rather than a God that came from nothing that was always there or "eternal". I agreed with the idea that it is human nature to want to know the cause of things and by knowing the cause one can find happiness. I think that God is a creation in the minds of humans who are seeking that happiness that can only come from knowlege of causation.
