'Primitive Machine' Within Great Pyramid of Giza Reconstructed

As someone who builds things similar in this era it's always interesting to see how things were done thousands of years ago. I just build houses not pyramids but a lot of construction principles were invented back then that are still in use today.
What a construction sitem that must have been!

At least you don't think it was the aliens. You have an hypothesis.
