Yeah that is the way I look at also. Every culture in every time, in every corner and crevice of the world has their own religion. The Greeks, Egyptians, African Tribes etc. They all believe(ed) truly that their supernatural god created everything. We now teach them as nothing more than ancient folklore. In it's place we now have Christianity, Islam, Hinduism, Sikhism, Scientology etc. What makes you think that Christianity is correct as opposed to say Sikhism? How do know that Greek Mythology isn't correct? Maybe an African Tribe got it correct with their beliefs?
I refuse to live my life by beliefs. Religion is just that, a set of beliefs that, as of yet, can not be proved or disproved. My money is on the Agnostic leaning toward Atheistic side. The mere fact that there are more than two religions means a large portion of people on this Earth have to be wrong.
