People also need to know that several gods in the Levant names we're spelled in Hebrew with only three letters similar to the tetrogramaton, YHD, ywh, yhu, yam etc. Also the oldest found writings of the tetrogramaton was also only three letters.
To this day experts are still fighting over who this God Jehovah really is. Did he start out as El, become Baal then get switched to another God by the Jews? Is he one of the sons of El? Its anyone's guess, so gods doing a piss poor job of making his name known.
