They have an internal and eternal moral conflict as all people do and there are basically two ways each person handles the reality of GOD'S existence. Rather than acknowledge God's renown, some people will substitute the personal compelling which humbly admits they are morally bankrupt for the pretense of having an intellectual conundrum with the patently obvious reality of a Creator, namely God. Others will readily admit God's existence as culled into a powerfully self-evident truth during childhood while laying on the grass or the like and pondering how they came into existence. If the atheist admits God's existence, he admits that there is a morally objective foundation by which he must be held accountable. Put another way, they are their own hostile witnesses and moreover they do what any crafty criminal does to the person who can testify against them and send them to prison. They eliminate the potential witness by any means possible. Most atheists I have clowned around with never admit that God doesn't exist. It is always "I don't know." So they're not atheist but agnostic. They have contempt for the God who they claim will send 99.99 percent of all people to hell irrespective of their beliefs. This is their wrongheaded logic anyway. I've read it over and over again. They forestall with "I don't know" and claim that science hasn't proven God's existence while also admitting that all human thought and sense cannot be trusted. However, when you pin them down on the unreliable human cognition that necessarily had to have created the scientific methodology, they will recant a bit and claim that in spite of untrustworthy thoughts and senses that the scientific method was still remarkably developed. They claim that no religion is the absolute truth but fail to see that when they make this claim that they themselves are claiming that they know an absolute truth. They fall back on Darwinism which has already been proven wholly false. Darwin himself admitted on page 92 of his own autobiography that he was a Theist.
Here’s the excerpt from p.92-93 of Charles Darwin’s autobiography:
"Another source of conviction in the existence of God, connected with the reason and not with the feelings, impresses me as having much more weight. This follows from the extreme difficulty or rather impossibility of conceiving this immense and wonderful universe, including man with his capacity of looking far backwards and far into futurity, as the result of blind chance or necessity. When thus reflecting I feel compelled to look to a First Cause having an intelligent mind in some degree analogous to that of man; and I deserve to be called a Theist." -Charles Darwin
