Interesting movie. What's the point you're trying to drive home @ 1:20:16? There's no god because some guy tripping on a hallucinogen didn't get an answer from Him when he called out? Or maybe that hallucinogens are not a good way to reach God?
Maybe he didn't think he needed God, because knowing God is concurrent with realizing that everything of yours, your life, the universe comes from God. LSD, like anything else, is just a means, fated among all the other swirling elements to do one thing or another, according to the will of God... I took LSD and mushrooms a fair number of times in my early teens, and I never found God.
