I don't know the history of astral projection but here are some thoughts.

I think humans had the ability to leave their bodies from day one (whenever that really was!). In my view, our souls are in our bodies and we own them, so if we want to move them out of our bodies, we can. Believing we can, knowing we can, are very important prerequisites, though.

I'll bet people had spontaneous out of body experiences all along. They may have called it something else though.
