god is not proven, mystic you cant prove him, i cant prove him and your arguments are hypocrytical because you try and argue that god must exist because some one had to create the universe, and that will always come down to who created god. as far as dissing other religions these are some interesting facts about the storys in your bible.
you can look up these religions on the net and look into the legends i mention here. they're storys along the same lines you find in your bible only they existed hundreds of years before the hebrews could even write
the sumerian religion has a story of a flood that was sent by a god named enlil to destroy human kind but one man and his family was spared. the egyptians had a similar story of a flood that was going to kill human kind until osiris decided to stop the flood sparing very little humans. both these storys existed more than a thousand years before the hewbrew religion was even born. now there is a story of the same sort in your bible its about this guy noah, the sumerians also had a story about these people that lived in a sacred garden but they were kicked out for eating forbidden plants this again is a story that existed long before the story of adam and eve in your bible.
