An atheist asks for evidence of God, and if they are not satisfied with the evidence, they maintain their claim, there is no evidence for God. An atheist, therefore, should have an idea of what would be regarded as evidence enough for them to accept that God exists, because an atheist knows, or thinks he knows, what is not evidence of God. The atheist does not think, or accept the idea that he is blinkered by his atheism. That his atheism prevents him from accepting God. So the atheist must think that he can know that God exists, and remain an atheist. I don’t think you can, which is why ask the question. Jan.
