Religion as a belief system goes back hundreds of thousands of years. So why are so many of the religious peoples of today so focused on a supposed God that goes back only 5,000 years? The answer lies in how our brains work.
Religion, and the mentality it brings, have arguably shaped the human species more than any other force. We don't understand it, and perhaps never will. We are so far removed from religion's creation (pun presented but not intended) that we have instead just woven it into our daily lives and accepted it as something we can't understand. This leads to questioning, mostly about what religion actually is and what is the "right" one. But instead of asking "what" religion is (e.g. is there a big man in the sky who lives in a cloud, or egads maybe that crazy science-fiction author L. Ron Hubbard had it right after all?!), perhaps we're asking the wrong question. Children seem to be born with an innate understanding of "souls" or at the very least the semblance of self amongst something greater - posits Reza Aslan - and this knowledge that religion is based on a literal primitive instinct should allow us to understand the question of "why" religion is. If you go back far enough, Reza says, you can pretty much pinpoint various reasons as to why religion is. It's an interesting video, and one that is sure to have you thinking about the subject matter much later. Reza's latest book is God: A Human History.
