"I think we’re aliens. I think we’re not necessarily native to this planet. I think we came here from somewhere else, destroyed ourselves a couple of times, and what’s left after all that period of chaos, that’s what we have left, and that’s why no one knows where the fuck we came from. The early part of human history and civilisation is riddled with unknowns. Where did we come from? Where did these ideas come from? How do the Egyptians have such an advanced civilisation? Well, I think it came from before and just no one remembers. (The) last Ice Age, when the sea levels rose 400 meters. There’s a whole lot of stuff sitting out there, covered by water that we have no idea where the fuck it is. What was there? Just imagine if you took our sea level right now and raised it by 400 meters, how much of our current civilisation would then be underwater? So what happened at the end of the last stage? How do we know what was before the end of the last ice age? We only have a few things you know left. So you know, and how much shit survives 10,000 years of natural decay? Not much. Why do we still even know about the Egyptians? Well, they managed to build some shit that lasted 1000s of years, right? Otherwise, would we know anything about them? No, we wouldn’t; or it just be speculation, hearsay, and rumour."
