Crazy idea but what if plants are actually higher lvl beings? They are more self-sustainable and helpful to ecosystem than humans.

Actually they probably aren't because I guess otherwise all different planets would have them (but hey we are also only here so far).

There's interesting question what would god-like(unlimited power over mater and limitless knowledge) entity do? I guess killing oneself and recreating with sprinkle of rng makes some sense after such event as you probably get bored thus I'm speculating that universe could be god itself (if it's bound by same laws of physics - if not then IDK). Don't ask me what I'm smoking :p
