The Great Pyramid is the only survivor out of all seven ancient wonders. Located in Cairo, Egypt, the pyramid still amazes thousands of scientists and guest's each year.
The Great Pyramid is believed to have been built over a 20 year span. The pyramid is so huge and so perfect we wouldn't be able to construct something in this day and age that will compare. Each giant Stone ranges from 1 to 20 tons in weight, and the Great Pyramid consisted of well over 100,000 stones. But the Egyptians had no machinery, engines, or construction equipment. So the question still lurks, who built the great pyramids?
Theories suggest the Egyptians built these pyramids, but this asks us how Egyptians hauled 20 ton stones and placed them perfectly Hundreds Of Feet high (145.75 m, 481 ft high).. Some suggest they built a ramp with stones that went from the ground to the top.
The flaw in that theory is that It would take More Rocks to build the ramp than it would to build the Pyramid. When the Pyramid was done, where did these rocks go??? So that shoots down that theory...
Another question is How did they move these rocks.. Experts that insist Egyptians built the Pyramid suggest, Trees were cut down and smoothed off, and were used as giant rollers under these 20 ton rocks. If you would roll a 20 ton rock on 5 trees, The tree would be too worn down and awkward to haul another, so these logs would be replaced every Stone. Due to the fact there are over 100,000 stones that make up the pyramid, you would need an excess of a half million trees..
Problem with this theory is the lack of trees in that area. Egypt grows some Date Trees, that's about it. And they certainly wouldn't cut down all their date trees, for dates are one of the main foods in EGYPT!
Now the Great Pyramid was the biggest and tallest of all the Pyramids ever built. Since the Egyptians left us an entire detailed written summary of every event in Egypt imaginable, You would think the building of the greatest Pyramid would be discussed. But it Isn't. The Pyramid was referred to a few times in very early Hieroglyphics. Egyptian writing suggests the Great Pyramid Was Standing Before Egyptians Populated The Land. Ancient hieroglyphics have detailed writings of farming, giving birth, Pharaoh worship, Hunting, Building Structures, etc, BUT the Building Of The Great Pyramid Was Never Mentioned.
If it took 10,000 workers per month over a 20 year span to build the Pyramid like experts suggest, There wouldn't be enough people in a 500 mile radius to make this possible.
Actually ancient Egyptian writing often talk of beings from the sky, the sky opening and bright lights coming down to teach them technology and give them wisdom. Many pictures and symbols resemble UFO's and aliens. POSSIBLY aliens built the Great Pyramid. And these solid long lasting construction techniques were adopted by the Egyptians.
