Jesus revealed in Luke 24:36-42; ghost does not have flesh and bones in vs 39.
Luke 24:37-48
[37]They were terrified, thinking that they were seeing a ghost.
[38]But he said to them, “Why are you alarmed? Why are these doubts coming up in your minds?
[39]Look at my hands and my feet, and see that it is I myself. Feel me, and you will know, for a ghost doesn’t have flesh and bones, as you can see I have.”
[40]He said this and showed them his hands and his feet.
[41]They still could not believe, they were so full of joy and wonder; so he asked them, “Have you anything here to eat?”
[42]They gave him a piece of cooked fish,
[43]which he took and ate in their presence.
[44]Then he said to them, “These are the very things I told you about while I was still with you: everything written about me in the Law of Moses, the writings of the prophets, and the Psalms had to come true.”
[45]Then he opened their minds to understand the Scriptures,
[46]and said to them, “This is what is written: the Messiah must suffer and must rise from death three days later,
[47]and in his name the message about repentance and the forgiveness of sins must be preached to all nations, beginning in Jerusalem.
[48]You are witnesses of these things.
