The Great Pyramid of Giza was built as a tomb for a Pharaoh more than 5,000 years ago. It probably took thousands of men more than 20 years of non-stop labour to construct. It was the tallest building on planet Earth for more than 4,000 years. It is the only surviving wonder from the Seven Wonders of the Ancient World.
The ancient Egyptian astronomers knew the exact location of that unknown place the religious like to call Heaven. Its location is in the northern sky, in the small group of stars known to the ancients as the Unconquerable, which are found in the vicinity what we call today the North Star or Polaris.
And the location of the final destination of the spirit or soul was surely there because this was the only fixed and unmoving point to be found anywhere in the sky. There, without a doubt, was Heaven. And there surely the Eye of God; the Masonic eye we see in many places today; on the paper currency of the USA for example.
What was earlier believed to be a ventilation shaft leading outwards and upwards from the so-called King's Chamber in the middle of the Great Pyramid is nowadays believed to be the shaft, or path, for the Pharaoh's soul to proceed through and then onward into the sky in the direction of its heavenward journey to the region of Polaris; there to be renewed.
A religion or cult with a precise location for its Heaven. Now that really is something out of the ordinary; but then that's really no surprise for those ancient Egyptians were an out of the ordinary people.
