Actually ancient Egyptian writings very often talk of beings from the sky, the sky opening and bright lights coming down to teach them technology and give them wisdom. Many pictures and symbols resemble UFOs and aliens. POSSIBLY aliens built the Great Pyramid. And these solid long lasting construction techniques were adopted by the Egyptians.
Ancient Egyptian legends tell of Tep Zepi, or the “first time”. This is described as an age when “sky gods” came down to Earth and raised the land from mud and water.
They supposedly flew through the air in flying “boats” and brought laws and wisdom to man through a royal line of Pharaohs.
