Abraham Taught the Egyptians about the Universe

Abraham 3:15

15 And the Lord said unto me: Abraham, I show these things unto thee before ye go into Egypt, that ye may declare all these words.

The Prophet Joseph Smith said:

“The learning of the Egyptians, and their knowledge of astronomy was no doubt taught them by Abraham and Joseph, as their records testify, who received it from the Lord.”

(In History of the Church, 5:63.)
