I've been reading a lot into the idea that the Egyptian empires existence could have dated back several thousand years earlier (water erosion on the temple sphinx). And the still debated Yanaguni Pyramids in Japan.
I am no expert in any of this and the extent of my knowledge is listening to Graham Hancock talk and then fact checking it with Wikipedia and other sources, so there is a good chance these may be all disproven among historians.

Okay first, the water erosion theory is crackpot science, and just does not match up with the archaeology of the pyramid sites. As far as I know, the erosion is from sand, not water.
While this is not directly related to your question, you might like (this documentary)[https://www.youtube.com/watch?v=Ws4O5LOCI68] on the Egyptian pyramids.
And the still debated Yanaguni Pyramids in Japan.
Wikipedia says it's debated, however, utilizing a bit of archaeology knowledge I can be quite confident that humans were not involved in actually building the site. Lookingat this picture is why. That rock is way too massive to be moved by human hands without being split into chunks. As far as it being "modified" by humans, I would not rule that out, based on what I know, but I would say its "unlikely".
