It made it MUCH EASIER (seemingly) to defend atheism—but you aren’t winning when you retreat from the field into a fortress, giving up the territory.
In brief, THIS CLAIM about lack of evidence WORKS ONLY IF the atheist is able to discount all the theistic evidence, by taking it as SOMETHING ELSE.
Usually the atheist will CLAIM to claim nothing, and then CLAIM THINGS, like “theism is absurd”, as in this specimen I just got:



IF there is a God, THEN it is rational to hold that God would have created human beings with rational faculties capable of discerning this. The cognitive processes that lead ALMOST ALL human beings to form a belief on God are UNRELIABLE ONLY IF there is no God.

The atheistic claim of insufficient evidence for God HAS WEIGHT IF AND ONLY IF THERE IS NO GOD.
So the atheist needs to establish THAT presupposition for his atheology to work. But he can’t. He ran away from it to the evidence claim, in fact.
1 Atheists began saying there isn’t enough evidence for God.
2 Theists began presenting evidence.
3 Atheists then said either the evidence presented was not evidence or to dismiss it as of little weight.
4 To do this, they needed to PRESUPPOSE a secular lens.
But is your secular presupposition itself WARRANTED? It is if there’s no God.
But THAT is what it would be necessary to PROVE.
