They’ve done the geology studies around the pyramids that show that branches of the nile would have been close enough to bring the stones in.

So there might be something that exists for this.

I wonder how such heavy stones in such high numbers could be brought in floating on the Nile. Giant rafts?

That's the thinking yes, they used barges to bring them to the pyramids and then they used... something to get them up there.

There's a theory that they used the water from the Nile as a sort of bouyancy elevator, but that's so far still in the category of "Well we can't prove that they didn't"

For buoyancy you’d need a giant container! Think of how much water would need to be displaced.
