>who benefits from a person not reuniting? the devil?

Or something we interpret as a devil due to our conditioning. 

>how does a person end up taking a spin in a body in the first place?

I think it's supposed to be a learning experience and people just get stuck in the physical world out of habit. If you complete your education and release the body why would you need to re-incarnate again?

the theory that aliens are recycling our souls

>some talk about reincarnation being this, you soul being recycled

Reincarnation is a trick to get you to choose to come back here instead of re-uniting with God. It works because people still have the habit of being in a body.
