Biblical circularity.

[Epimethean]

"But there is, however, the thorny problem of accounting for and explaining objective reality consistent with your atheism (the problem being, of course, that you cannot do so). Of course you presuppose objective reality, along with pretty much everyone else, as do such things as reason, knowledge, and science (i.e., their intelligibility rests upon objective reality), but your atheism cannot account for it. In other words, you believe there is an objective reality but you have no valid justification for that belief consistent with your atheism."

There is no "thorny problem" there whatsoever. The abandonment of superstition is its own evidence that we are evolving away from a need for supernatural aetiology.
