"Passing the veil does not alter a man; it certainly takes him from the eyes of flesh, but the capacity, the intelligence, the thinking powers, are all alive and quick; and if they hear the Gospel they will be glad, and the promises are made to them, and they will rejoice in them."

I suspect there could be life and intelligence out there in forms we can't conceive. Just as a chimpanzee can't understand quantum theory, it could be there as aspects of reality that are beyond the capacity of our brains They could be staring us in the face and we just Don't recognise them. The problem is that we-re looking for something very much like us, assuming that they at least have something like the same mathematics and technology.
