Just ignore him and press on.
To answer your OP, the short answer is: you aren't having a crisis of faith, you're just smart enough to realize that the whole concept is dumb (mind you, that's not a hard bar to get above). The entire notion is a construct of humanity to explain things we didn't have explanations for. As time has gone on, less things relevant to normal day-to-day life are left un-explainable in ways people can understand, so the role of a higher power has shifted into purely a tool of control, or a final answer for 'why' for the remaining people searching for it.
I'll note there's still a subset of people as well that believe in a higher power, but no established religion. Those are the people I'd classify as 'agnostic' if one is required to use such a term, and in my mind, it's defining people still searching for a higher power, but acknowledging it's none of the established ones. If my mind were to meander into simpler places, and I were looking for such a 'final answer' in the form of a power greater than myself, it'd either be the creator of a simulation (if we could prove that, or if it's even relevant), or it would be Math. Math is the handwriting of the universe, and everything that has, does, and ever will exist is created by it.
Everything that we've ever defined is a human construct, that includes the concepts of right/wrong, morality, emotions, and thought (arguably may constitute consciousness, which I believe is an end-result of math, so may not count as a human construct).
If you want more information on the direction I'm moving, check out the book 'Our Mathematical Universe' by Max Tegmark. Very approachable for 95% of it (for anyone on this board), and provides compelling evidence, and thought experiments, for the existence of a math-based reality.
