"Why am I here?"
"Is this all there is?"
Please tell me a religion, even atheism that doesn't provide the answers to those two questions.
Yes Bret, it really is that simple if you think about the humans who first pondered the two questions and their own existance. What more do you need to know to determine if you believe in an omnipotent being or something else?
I hope every sentient human who has dealt with those two questions are comfortable with their own personal answers. The answers are personal and can be as different as the number of people who have asked or been told the answers.
What else would be the basis for any religion if those two questions were never asked or considered?
