They seem to have been masters of both the spiritual and physical sciences. Egypt in Egyptian was "Khemit" (or some variation on that spelling) which means "black powder." I hear some people saying it meant "black land" but it's powder - they assumed it was land because of the Nile in a classic case of mainstream archaeologists F'ing stuff up. Our modern history tells us we got black powder from the Chinese, but to the Chinese it was a secret alchemical formula, mainly used in healing. Where'd they get it from? Khemit... Early Egyptians had technology. Later/dynastic Egyptians were primitive compared to the pre-dynastics.

Spiritually, we can read what they believed... They believed in reincarnation, that after death, your soul went into a lake of fire to be remade. They had a holy Trinity - Osiris, Isis, and Horus, and Osiris was resurrected from the dead after his brother Seth (mentioned in Genesis as 3rd son of Adam) killed him. You could escape the reincarnation cycle by going to Amenti instead of the lake of fire if your heart weighed less than a feather. Err, they could. Their earthly lives were viewed as actually a death, a temporary state, which was supposed to perfect them.

Well anyways. Fascinating people...
