Except that Jesus isn't "like" God, he *is* God.
The name Michael can also be understood as a rhetorical question -- "Who is like God?"; the correct answer being, "Nobody". I believe this is the traditional Hebrew understanding of the name.
Jesus' "pre-existing name"? YVWH, of course.
If you read Isaish, Christ had several names.
Who is like God, is a title and statement and not a question. You’d have to show it was intended as a question and not a statemnt for it to not be correct.
