What the Ancients Didn't Know?

I'm just curious about what the ancients knew. What was their context for all this? You mentioned the pyramids. Maybe we can talk about that. The pyramid is not only supposed to be an artifact machine, but also a calendar of sorts. So to bridge so many conclusions from so many disparate data sets, we basically circle back to the oldest traditions and find like in the old Sanskrit texts and in the Vedic belief system that our reality was like an illusion.
