You are correct.
But Jesus Christ didn’t go into space.
Moving something from one location to another is not the same as the spirit of Christ ascending to heaven.
I am only trying to point out that IF they found the physical body remains of Jesus of Nazareth, it doesn’t mean Jesus Christ didn’t ascend to heaven.
This is fun. Check out Acts 1:9, “And when he had spoken these things,while they beheld, he was taken up; and a cloud received him out of their sight.”
