I've learned of atheists throughout history. Democratis, the Greek, said that if god is all knowing and all powerful, it can't be all loving. All powerful and all loving, it can't be sll knowing. All knowing and all loving, it can't be all powerful
Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?
— The Epicurean paradox, ~300 BCE
But, What is Evil? What is omnipotence? and What is God? What would it mean to say that God is Willing? These terms come from primitives with an extremely limited scope of understanding. You may as well be talking to your dog. And that's still true with most people today, except that people today have chosen to be idiots, rather than actually learn about the world. It's their loss, but they impose their ignorance on the few who revere Truth.
