I do respect your concern. That very issue led Apollinarious in the 4th century to suggest that Jesus wasn't ever truly human, that he only seemed to be human. Of course, the Church has always held that Apollinarious and the rest of the Docetist were in error. The Docetists for their part, argued that the idea of God taking on human flesh as an innovation of human minds.

But, according to scriptures, this is not something that humans created. This is something that God himself chose to do. It is he who took on this nature. It isn't us depicting God as human; it is God inserting himself into humanity.
