Per the Nicene Creed:
He came down from heaven
Per the Holy Bible:
No one has ever gone to heaven and returned. But the Son of Man has come down from heaven.
He has come from above and is greater than anyone else. We are of the earth, and we speak of earthly things, but he has come from heaven and is greater than anyone else.
After everyone was full, Jesus told his disciples, “Now gather the leftovers, so that nothing is wasted.” So they picked up the pieces and filled twelve baskets with scraps left by the people who had eaten from the five barley loaves.
When the people saw him do this miraculous sign, they exclaimed, “Surely, he is the Prophet we have been expecting!” When Jesus saw that they were ready to force him to be their king, he slipped away into the hills by himself.
That evening Jesus’ disciples went down to the shore to wait for him. But as darkness fell and Jesus still hadn’t come back, they got into the boat and headed across the lake toward Capernaum. Soon a gale swept down upon them, and the sea grew very rough. They had rowed three or four miles when suddenly they saw Jesus walking on the water toward the boat. They were terrified, but he called out to them, “Don’t be afraid. I am here!” Then they were eager to let him in the boat, and immediately they arrived at their destination!
The next day the crowd that had stayed on the far shore saw that the disciples had taken the only boat, and they realized Jesus had not gone with them. Several boats from Tiberias landed near the place where the Lord had blessed the bread and the people had eaten. So when the crowd saw that neither Jesus nor his disciples were there, they got into the boats and went across to Capernaum to look for him. They found him on the other side of the lake and asked, “Rabbi, when did you get here?”
Jesus replied, “I tell you the truth, you want to be with me because I fed you, not because you understood the miraculous signs. But don’t be so concerned about perishable things like food. Spend your energy seeking the eternal life that the Son of Man can give you. For God the Father has given me the seal of his approval.”
They replied, “We want to perform God’s works, too. What should we do?”
Jesus told them, “This is the only work God wants from you: Believe in the one he has sent.”
They answered, “Show us a miraculous sign if you want us to believe in you. What can you do? After all, our ancestors ate manna while they journeyed through the wilderness! The Scriptures say, ‘Moses gave them bread from heaven to eat.’”
Jesus said, “I tell you the truth, Moses didn’t give you bread from heaven. My Father did. And now he offers you the true bread from heaven. The true bread of God is the one who comes down from heaven and gives life to the world.”
“Sir,” they said, “give us that bread every day.”
Jesus replied, “I am the bread of life. Whoever comes to me will never be hungry again. Whoever believes in me will never be thirsty. But you haven’t believed in me even though you have seen me. However, those the Father has given me will come to me, and I will never reject them. For I have come down from heaven to do the will of God who sent me, not to do my own will.

Truth is...the idea of coming "down" from or going "up" to heaven may be a bow to our limited, human understanding, so let's not get all excited about getting in a rocket and blasting out into space looking for a physical place called heaven. The point being made is that Jesus existed in a purely spiritual "form" before being birthed on Earth having taken on the form of a human being. (Philippians 2:7)
