This wouldn't be proof that God exists though... proof of God's existence is probably impossible. I mean, hypothetically, if God exists and is willing to do anything to show us he exists, how would you or I verify he exists?

If we were somehow satisfied, how would we satisfy others? Even photos / videos wouldn't be enough as there'd always be claims they were faked. Photos / videos in combination with some sort of unprecedented global weather phenomena may be the best bet but even then science would be falling over itself to explain what happened and wouldn't just accept that yep, god exists and is responsible for that.

Proof of my and your existence is impossible in a similar way - we could all be just brains in vats and all external stimuli might be hallucinations (or we could be just GPT-powered chat bots). In fact, I could be a hallucination of yours and you could be my hallucination. While the idea of solipsism is sort of an interesting thought experiment, it doesn't really help explain or predict anything.
