I watched some guy (I can’t remember the name, sorry) talking to Jimmy from Bright Insight about this. Apparently they’re all on some oblique line of latitude if you tilt the earth a certain way, and all line up. He mentioned how in today’s world you’d find skyscrapers in America, China, and Europe because you effectively have a global society, so that fact that pyramids are widespread must mean there was something akin to a global society back then as well.

He also nerded out hard on the concept of the simple bow and arrow, and the engineering that would’ve gone into it. Finding the right type of wood, the coatings required, the right material for a string, curvature and the angles involved. Not to mention arrows themselves; the size and shape, the penetrating power of different tips, adding feathers to the ends to make the arrow spin in flight. He said in his opinion it was absurd that we’re taught the Egyptians, the ancient Chinese and the Cherokee all came up with the exact same invention by accident, with the exact same engineering involved and built on the exact same principles, all while on opposite sides of the world from each other. No one really knows where the bow and arrow came from, it’s just something every society just always “had”. He said in his opinion that was more proof of ideas/knowledge/technology crossing the world as the ancients travelled.
