You can't prove God didn't create the world in 7 days any more than you can't prove the Flying Spaghetti Monster did that 15 minutes ago.

That the Earth is not flat is easily and conclusively provable.

Of course I can't. I thought that the onus of proving is in the court of the ones making a statement.

What is the standard of proof here? I'd that the standard seven day creation story is about as outlandish as the narrative that the holocaust is a big hoax.

Is it technically possible to explain away all the evidence with sufficient effort? I suppose. But occams razor tells us that yes, the holocaust happened, and no, three days did not pass before the sun was created.

My point is that we generally don't expect mathematics-like incontrovertible proof to establish historical fact, and it's unfair to demand it to disprove religion. More broadly, Facebook now has to figure out what the standard of proof is for their platform.

In their shoes I'd draw the line at "advocates for killing people". Seems reasonable enough.
