There are two groups of atheists who do not really believe in the existence of God and the rest of subtle matter and those who are ardent adherents of atheism. The second group of atheists preach their atheistic views as a religion . These are the fanatical atheists hate God and all that is connected with it.
Why won't they see God ? Maybe something happened in their lives, and they were waiting for God's help, but did not get it, now they broke up and got angry with God. There was already a similar topic on the question: 'Atheism is an offense to God?'.
Maybe fanatical atheists are missing something in life, namely God. They understand that, but buduci hard-nosed people who don't want to admit their mistakes. Therefore, they throw out their hatred on God and those who believe in him, and it becomes easier for them on their non-existent soul.
Do you see God? What he looks like?
If you see him, you are insane.
BTW, most atheists do not believe in God(s) because of the lack of physical evidence.
Typical ape brain response, which btw isn't true. Plenty physical evidence for The Creator, for example Flat Earth...
