What were the pyramids?

Nobody knew until now. This kid on Youtube with 25k followers has it figured it out, or at the very least got close to it.

The pyramids were a chemical factory for fertilizers and chemicals like ammonia.

Not a spaceship, not a time machine, not an interdimentional portal, and definitely NOT a tomb of Pharos.

This is why I am so bullish on online creators, they are the future. If we could only help him fundraise to do some ACTUAL RESEARCH!
