The fact that there is no evidence does not negate the possibility.
By the same math using the same weights the same can be said of any human conjuring. Flying Spaghetti Monster, Invisible Pink Unicorn (MTABTOIHF)
*, Great Green Arkleseizure, Aphrodite, Cthulhu.
Since this universe doesn't seem to show these human conjectures as having any reality we can assign the same possibility and legitimacy to each. Vanishingly small so as to be non-existent. And with no discernible, demonstrable, effect or attributes from these entities on anything in our universe we can assign a utility of zero. They are worthless to us.
"Possibility" only requires a wishful glance and means nothing. Evidence, even the lack thereof, requires fact and is everything.
