The list you gave is repeated on the web in many places in support of alternative pyramid theories. They have been discussed here and in other places, and most shown to be either partially presented/misrepresented facts, or just plain incorrect.
Starting with an easy one...
10. The great pyramid is NOT at the center of the earths land mass.
The earth is a sphere, not a flat plane, therefore the center of the earths land mass is somewhere near the center of the earth itself.
This is the diagram usually given in support of the claim...
This is NOT a 100% correct representation of the earths land masses... it is a projection. Try peeling an orange and laying the skin out flat. You won’t get a nice neat square, like a map. The ONLY way to represent the surface of a sphere on a FLAT surface is to distort some areas. Look at Greenland on the image above, it is nearly as wide as North America.
Here is some info on map projections, the one above looks like a Behrmann cylindrical projection, look at the distance between the equator and the 30' latitude line, then between the 60' and 90' lines. This is NOT an accurate depiction of the entire earth's land mass.
Furthermore, the ONLY reason lower Egypt appears near the hypothetical 'land mass center' on this map is that the projection is CENTERED on Egypt's meridian. Take another projection centered on any number of different latitude and longitude combinations and you will get a different 'land mass center' each time.
