Jesus was the word made flesh,but he did not leave heaven.
John 3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
I couldn't believe that KJV was worded like that. So I had to go check it. Still after comparing with other Bibles, I don't disagree with it. The word "even" is sometimes
used as "except"

John 6:38;
"For I have come down from heaven, not to do My own will, but the will of Him who sent Me.
1 Cor 15:45; So also it is written, "The first MAN, Adam, BECAME A LIVING SOUL."
The last Adam became a life-giving spirit.
1 Cor 15:46; However, the spiritual is not first, but the natural; then the spiritual.
1 Cor 15:47; The first man is from the earth, earthy;
the second man is from heaven.
I suppose it could be debated who the second Adam here is.
Luke 10:18; And He said to them,
"I was watching Satan fall from heaven like lightning.
Apparently Jesus was in heaven at some point.
