Most religious belief is based upon information received from an outside source that cannot be verified, sometimes known as hearsay. Millions will follow the commandments of a religious text without ever having spoken to its author, and billions will believe in a deity because of miracles they were told of by someone who wasn’t even present nor alive at the time.
But denouncing faith is true folly. Faith is not limited to religious believers. While even the most devout pontiff cannot provide irrefutable evidence of his god’s existence, neither can the scientist who claims that no deity resides in the universe. Both rely upon their own faith to explain things they will never understand.
There is no proof of God. There is no proof of no God, either. If science cannot definitively prove that there is no God, then science has no choice but to accept a possibility of a god’s existence.
