It seems that it indeed is so that the apple never falls far from the tree. This is possibly the most idiotic seriously-made argument for the existence of God that I have ever heard:
"The essential proof is that without God you can't even know anything, and I would challenge the very basis of their world view saying, well, how can you argue against God, because very argument you are going to make against God is going to assume God. It would be like me arguing against the existence of air; I gotta use air to make my argument. Or me saying: I don't speak a word of English. Well, you just did. Every argument against God has to assume God. It assumes consciousness, it assumes thought, it assumes logic, none of which can be accounted for apart from God."
Either he is completely delusional in believing this is a valid and convincing argument, or alternatively it's enough for him to make believers think that it's a valid argument in order to get credibility, praise and attention (and that way indirectly monetary benefits). So he's either delusional or a conman. Perhaps a mixture of both.
