IMHO the theory that pyramids were built by predynastic civilizations is Swiss cheese.
Pyramid building in Egypt was surely affected by predynastic and civilizations outside Egypt but there is no shred of evidence that points to any pyramid in Egypt being erected before the IIIrd dynasty.
The only evidence, some of my friends can point to, are examples of disbelief. No prof of any kind. Though it is intriguing, and in this arena acceptable. Without it, we likely would not have this forum.
Until more than disbelief is used, I stay grounded in current beliefs. If anyone can prove me wrong, have at it.
