I am not saying that Jesus is one of the created angels. I'm saying by virtue of definition and for purposes of identifying him in the Scriptures, Jesus is called Michael the archangel. The bible never teaches that Jesus was made God from being an existing angel. But an angel is a messenger, that is the definition, and Jesus is the Word and he is the one who exercises the power, cause and effect of his words and delivers it to us. He is the messenger in chief and lord over all angels, both heavenly and on earth which is the definition of arch angel which identifies Jesus as Michael the archangel.
Later you will see that Michael is also the "prince" over Israel performing the prophesies we have been told the Lord Jesus will do, delivering Israel, reviving the dead from their graves to everlasting honor and dishonor, subduing and destroying the devil, etc. The Scriptures let us know with no mistake that Jesus is also called Michael.
