Would atheist worship The biblical God if his existence was proven?

[Fidel_Castronaut]

So does that mean that anything anyone imagines at any given point in time has to be taken at face value with an equal degree of certainty and uncertainty?

No, it just means that if you don't know whether something exists or not (i.e. no evidence either way), you can't be completely sure it doesn't.

Which leads to the logical conclusion of everything being possible, including me having sex with you when you're asleep. But every time you wake up, I'm back at home having sex with a female version of myself.

Possible, no?

The lack of evidence, coupled with the absurdity of the claim and the knowledge that it contradicts reality as we know it renders the claim moot.

The more logical position would be that of pragmatism, in that if we were to discover a state or expand our knowledge of reality to the point where such an event occurring were not just imaginable (some how) but possible, then we could accept it as potentially true. Indeed, this is the position I hold, but as currently the claim invalidates reality as we know it (or could possible know it), and has nothing to back it up aside assertion, it is false, and I can dismiss it with the same confidence as it was proposed (asserted).
