There is only one circumstance that I believe in God, when I'm withdrawing from alcohol and having panic attacks I will believe in God. It feels like absolutely real belief. Totally sincere. I even got baptized once when I was quitting alcohol(which I have done many times).

The moment I stop having desperate panic attacks that feeling goes away immediately. The moment that my mind is not in hell there is immediately no God for me again. I am an atheist if I am feeling fine.

God is for the biochemically weak.
