They claim their God has all power. They are wrong because only the all powerful all has all power. Their God does not even match up with actual evidence of our reality. The all powerful all is the actual evidence. They claim their God is truth but only actual truth is truth. The All powerful all is actual truth. It is not anything other than actual truth.
I am an atheist because of actual evidence that all that is actually exists and there is evidence of the all powerful all.
