The Great Pyramid was made by Pharoah Khufu and is the largest pyramid in the world.
My friend also told me that the formation of the pyramids of Giza (birds eye-view) is the same as a rock formation on Mars. How creepy is that?
The first picture is that of the craters of Tharsis on Mars.
The second is that of the pyramids/
The third is a comparaison of their locations.
The first picture is that of the constellation Orion's belt, then that of the pyramids and lastly their comparaison.

Isn't that cool? It may just be a coincedence but...what do you think?
Ciao, ciao!
