Everyone here has it right, God did not create any religion. There are still 'new' religions being formed today. The older ones have altered their ways to adapt to modern society as well. If you look back into history, you will see how various cultures had different ways of worship.
It is interesting to note that just about every culture worshipped something or someone so it certainly makes a case for some form of higher being. If that higher being created us, they made sure that we had minds of our own that come to their own conclusions and that also speaks volumes to me.
Humans are funny, fical (sp) creatures and we all want to be right, too bad we can't be!
