Read your Bible. Most Christians don’t know about the Resurrection of the dead and the 1000 year reign and the new earth.
We will not be floating spirits with a harp. We will be perfected in the flesh eventually and the soul and the spirit.
Did not Jesus show he has a body that could be touched and did he not eat?
