How about....
there are multiples of ourselves all scattered out through time and space, some could even ran into their duplicate, raised by different parents in another land, just because GOD so loved his people, that he seeded them all over this place, placed children into mother's wombs just to make sure, that there would be enough us's to help in these trying times?
Would this be ethically correct?
Have you ever felt or witnessed someone seemingly out of place being raised in a family that didn't appear to be their own?
Birds can do it, humans can do it, too.
