You know not of what you speak. The great pyramid in Egypt is an engineering marvel which we cannot duplicate to this day. The precision is incredible.
All you have to do is look at a few others they created to see how hard it is to build. The others are nothing more than a pile of rubble.
"Im surprised every continent on earth doesnt have pyramids. Put some stones on the ground and then put fewer stones on tone of those stones and so on and so on. Pretty simple. A pyramid is a glorified pile."
You are quite the intellectual. The Great Pyramid at Giza was the world's tallest building for thousands of years until the Eiffle Tower was built. And archaeologist still are not exactly sure how the Egyptian manged to build their Pyramid with the limited resources available to them.
There are pyramids on all (habitable)continents except Australia.
Mexico has more pyramids than all the rest of the world combined. Greece has 16.
