You continue to show your total ignorance of Biblical history. "El or Elohim" was FIRST name that was given to mankind by God in the Garden of Eden. In Genesis He revealed a second name to Abraham: "EL Shaddai" - "God Almighty", But in Exodus, He reveals another of His Names to Moses (Moshe). Exodus 6:2-3 : And God spoke to Moses and said to him: "I AM the LORD. I appeared to Abraham, Isaac, and to Jacob, as "God Almighty", but by My Name LORD I was NOT KNOWN TO THEM. LORD is the English for YHWH.
This more readily explains the differences in the name by which God is addressed in the different texts.
There are, of course, theological explanations of all that.
And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.
Christ did the same in John 8:58:
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I AM.
