Indeed. The truth may just very well be strange and most will not handle it.

What if we all came here by choice. Sort of a vacation from reality. After all, our "souls" survive for eternity, passing from one vessel to the next, learning, performing your duties but at some point, it all becomes routine. Erasing all past knowledge before passing to this body enables us to experience life once again. To see with new eyes, different points of view and recharge our "soul".

Et's may have a hands off approach to the human experience but ever so closely watching to ensure we don't ruin it for everyone else. Sort of a galactic melting pot.

Now, if this species starts destroying this world and every bag of tricks has been used to divert disaster with no results. It would seem to me, genetic manipulation may be the only recourse.
