SJSinNMYC, do not think you know it all because you are MO. I am a BT with a very extensive secular education. I was brought up as a militant atheist.
There ARE proofs for athiests. The counter-proofs are like the staffs of the Pharo’s servants. If one wants to see the truth, one could. If one does not, one could deceive oneself, as Pharo did.
If there were no proofs, how could a person be faulted for being a kofer?
