He doesn't seem to grasp, even remotely, the concept of FAITH, and why people need it, or how it helps people function in a significant way, in their lives. All he talks about is the lack of material evidence for the conceptual icon he had in his brain, labeled "God".
The real problem here is that he grew up in a religion that touted belief in a conceptual religious icon, instead of faith in a great and inexplicable mystery. So he thinks he is an atheist, now, because he rejected belief in the religious conceptual icon he was taught to call "God", when in reality he has never had nor developed a realistic, functional, concept of God. Nor has he ever placed his faith in that concept to discover how faith in the reality of God, helps people. If we asked this "atheist" if love is real, and if trusting in love helps people live better lives, he would certainly agree that it is and it would. And yet this man obviously has made no connection between God, and love. Or God and beauty. Or God and justice. Or God and individual purpose. And why hasn't he? Because the idiotic religion he was raised in only taught him that God is a religious icon, and a religious story, in a religious book. So for him, God was never made real. And the moment he tested that God, it became apparent to him that it wasn't real. And now he thinks he's an atheist. When all he is, is just ignorant of the reality of God, thanks to a religious experience that taught him to "believe in" a religious fictional story of God as if it were the reality of God.
And this s the case with the vast majority of people who call themselves atheists these days. The truth is they never had any idea how God can be real to us, because religions are so woefully inept at teaching people how to recognize the reality of God in their lives. They're too busy, instead, trying to make people "believe in" the trappings and icons and dogmas of the religion.
