Both of you could be straining at a gnat while swalowing the camel.
God’s word clearly says there is such a thing as a ghost (disembodied spirit).
What do you think Christ cast out of the insane man and allowed to enter the swine herd?
Enoch states that the demons are the disembodied spirits of the offspring of the union between the watchers and human women.
As to Moses, why would the creator of the universe have any difficulty bringing Moses and Elija to the mount?
He brought Lazrus back from death and decay, and a few others too.
I know that what people call ghosts are actually demons masquerading as ghosts.
God would not have any difficulty in providing bodies for people who have died.
Moses having a body is not evidence that he did not die since all believers get new bodies anyway.
