Look at the Tefillin. And the cube of Ka'aba.

Abrahamic Religions had some way of knowing the importance of this shape.

I personally think we had some serious help, back then. Which one might call Enki/Enlil/Annunaki, or whatever. But the Arc of the Covenant is obviously a nuclear reactor, the chariot in the sky in Ezekiel is obviously a "flying saucer", the Seven Seals are the Seven Chakras of the Kundalini, the Leviathan is in the Bible and Sumerian mythology, etc, etc. And on and on.

Of course I make these statements to be provocative. But I am like 90%+ the way to believing all of it.
