NightHiker beat me to it:

"If it's not the truth... then it's fiction."

If it's unsubstantiated opinion, it's probably still just opinion. That isn't fact or truth. If you firmly believe that spontaneous generation happens, it still isn't truth/fact.

There are too many totally different religions for all (or any) of them to be fact/truth.

Are you bored today, Dweste?
