For a pyramid to be "half an octahedron", its height must be the width divided by sqrt(2). Examination of the List of Egyptian pyramids shows that this is not the case. E.g., Sneferu: 220/(105*sqrt(2)) = 1.481557 Khufu: 230.3/(146.6*sqrt(2)) = 1.110823 Menkaure: 103.4/(65.5*sqrt(2)) = 1.116257 i.e., they are flatter than "half an octahedron".
The three great pyramids of Giza are not in a straight line. The two largest pyramids are arranged Northeast-Southwest of one another. The 225-degree line of bearing through Giza (NE-SW) does not even pass through South America at all, much less through Peru. The yellow line below is this bearing:
Well the answer is they didn't. The pyramids were built by pulling blocks up on ramps. ^ that is probably what it looked like.

The second theory centers on Herodotus's machines. ...
