Been saying this for years mate. The pyramid thing alone should've had mainstream archaeology asking serious questions decades ago, but they just keep trotting out the "independent invention" line like that settles it.
What gets me is the maritime capability angle. We know the Egyptians had ocean-going vessels, that's documented. The Ra expeditions proved the reed boat tech worked across the Atlantic. So the idea that nobody made that crossing in thousands of years of civilisation is just... a bit convenient isn't it.
The cocaine and tobacco traces found in Egyptian mummies is the bit that really nails it for me. That stuff doesn't grow in Egypt or anywhere near it. Someone want to explain that without contact? Go on then.
Interested what others think about the timeline though - are we talking Old Kingdom, New Kingdom, or is this potentially much older contact that predates both civilisations as we understand them. Theres a chunk of history before 3000 BC that we basically know nothing about.
