But I never claimed it was because I don't believe in it. I said it was mythology because it's clearly a man made story, the separate components of which were taken from various other influences over time, not the written down word of a super-being.

Anyway, in the end, your statement is backwards. The correct statement is that belief in something doesn't make it true. Proof of something makes it true. Until it's proven, you can't claim it as fact.

If I claim that something is true, then the burden is on me to prove it's true if I'm going to make that claim. But, for some reason, with religion, it always seems to be the other way around, that it's the burden of everyone else to disprove it. I've never understood how that gets turned around like that.

If you can claim it's true without proof, because lots of people believe it, then Islam is als true and Bhuddism is also true and so forth.
