It is just a guy tracing outlines on the moon and making absurdly hilarious conclusions. He sees a mining crawler like worm(sorta looks like khans ear worm things) the size of New York, a castle with battlements and a big cannon, a satellite dish that suspiciously looks like a crater *gasp*, and that's just the beginning. He also does a breakdown of some mission patch that clearly supports all of this. I'm not sure if I ever heard a "why" but this is just one of many.
There's a ton of them with all sorts of different "energies" and I've become especially fond of "the pyramids were energy producing batteries" thing recently and have just started looking at the "Siberian holes" are.... well they've never been clear really. Got any good ones?
