How could you possibly know such a thing?The powers of human reason.
Are you God?
Yes. I am master of my own destiny. I am my own God. And no, I have not been struck by lightning.
Not to discount the power of human reason, but you as a finite human being, have not and cannot examine all of the evidence concerning religion that exists. Since some unknown fact may prove your limited understanding of religion to be mistaken, you cannot be certain that all the evidence is in support of your position. Thus you are in no position to positively assert that
all religions are equally false, unless of course you were God, and therefore omniscient. That's why I asked.
Cordially,
