That is such a low-brow conclusion, typical of people in the Dark Ages.
I welcome your speculation. Have any ideas to share, low-brow or otherwise?
Not necessarily.
Secular people have lately begun to speculate that these "others" seem to be having a deleterious effect on those humans observing them and that this effect might be characterized as "not well-intended" or even "evil."
That statement indicates that you believe religious faith is something only humans living in the Dark Ages would have...and that is not at all true.
Think outside the box and you will realize that a lot of scientists and people of high intelligence are men of faith.
