Uncovering the Shocking Truth about Ancient Civilizations and the Pyramids

Many have wondered how one of the seven wonders of the ancient world managed to be built at all. Were they really so smart that they came up with a solution five thousand years ago while we cannot manage to come up with a sound theory today? The Great Pyramid of Giza alone is made up of two million three hundred thousand stones, and its engineering is mind-boggling, so it makes sense that we're a little skeptical. Another theory that we've managed to come up with is that human civilization may just have been even more advanced in the past, and that something like an asteroid impact may have set us back. Basically, this is the Younger Dryas Impact Theory, which claims that humans had reached a high level of sophistication but were struck by comet impacts, and the impact caused everything on Earth to obliterate. Another civilization emerged again, but at which point we had to start from scratch.
