I have, multiple times. Abraham escapes the clutches of the Egyptian religion proving his God is more powerful than theirs. The facsimilie representing such are changed in meaning to hide this fact. The meaning simply being lost over time is also plausible.
You proved what? Woe man. Abraham in the Bible can only be presented as a faith based myth at most. There is no real evidence of Abraham as there is for the great kings of Egypt which left not only records but tangible artifacts. You cannot say that the stories about Abraham in the Bible prove that Jehovah outperformed the gods of the Egyptians. Likewise, the same can said for Moses. There is no proof that Moses was even in Egypt doing the things your biblical record says he did. Hence, the Bible is not proof. It's faith based stories without tangible evidence. So don't throw out the "proof" word so fast.
Science has proven that Joseph Smith was a fraud because science has proven the truth about Egyptology. I guess you don't care for science very much, bcspace.
The idea of Anubis being called a slave by priests & scribes of the Egyptian state is utter blasphemy and is 100% NOT plausible. Case closed, the Mormons lose.
