The 'what' evidence is being asked for in order to define 'who'. You gave that evidence as 'knobs'. How do the knobs identify a unique culture who built the pyramids? All we see is that you compare the knobs to other knobs, which happen to be other knobs in cultures in different parts of the world in different epochs. Thus, according to your post, these 'other' knob makers would be the cultural connection to the pyramids of Egypt.

Thank you. So as you now agree the Inca didn't build the pyramids for these very good reasons, who would you say did?

If you don't know, it is because 'knowing' requires information. You don't know because there is no information, i.e. no evidence. I think you may be understanding now. :)

Archaeologists having been looking for a long time, and there is nothing there. Until such time as new evidence is found, the claim that the AEs did not build the pyramids cannot stand. A claim needs the evidence first, not the other way around. :)
