Atheism requires an active belief system. Since no absolute evidence refutes God’s existence, one is required to reject (and reject and reject). A belief without absolute facts requires faith. Does your faith and belief make it true?
OK, let's see how logical that is:
A-unicornism requires an active belief system. Since no absolute evidence refutes unicorns' existence, one is required to reject (and reject and reject). A belief without absolute facts requires faith. Does your faith and belief make it true?
Nope. We're not required to try to prove a negative. OTOH, you have the positive belief, so you do require either positive proof (or at least good positive evidence), or else you're left with having to actively sustain your faith.
So if someone makes the positive claim that 'A' is true but the evidence that is supposed to support that claim doesn't convince you at all, what do you believe? Especially if there is no way to show that 'A' is necessarily false?
Should we believe every unfalsifiable proposition?
