This was repeatedly and specifically replied to over and over again. The number of deaths from attempts at those activities was repeatedly pointed out. You're trying to suggest that modern humans taking greater precautions when engaging in those activities somehow makes it irrelevant that we still willingly participate in those activities because of the potential rewards.
You give no reason to assume the demons would have this level of sophistication. You just ignore every comparison given and then toss on the word retard. Every piece of information we're given on them suggests no organization beyond that of a pack animal and no technology whatsoever.
Alright, let me dumb this down for you. Hundreds of years ago the earliest reports of alien abduction were all being recorded as demonic visitation. Night terrors, sleep paralysis, incubus and succubus, the stories from that period are virtually identical to those of the alien abductees of the last hundred years. Frozen in place, taken away by strange creatures, probed, violated and in some way sexually assaulted. Now I'm not by any stretch claiming these things were real, I'm just saying an obvious link between the phenomenon has been drawn by many people, and I'd assume that's where whoever wrote the movie got the idea.
We never see any space ships, just crop circles and lights in the sky. The "aliens" have no technology, only abilities found in predatory animals. They don't really seem to have control over the portals either as they can't walk through walls or teleport around once they're here, as we see they're easily trapped by little more than wooden doors.
From there, we have dozens of possible explanations. Maybe they're little more than animals dropped onto a random other planet through no volition of their own. Seeing as it's suggested this happens every so many years more likely it's a cycle and they're sent to other planets and have no control over what hazards may be found in the latest planet they have to gather food from.
They could be drones manufactured in vats, remote controlled bodies, a physical manifestation of incorporeal beings who don't care if their bodies are damaged, worker drones in the equivelant of an insect colony. They could literally be traditional demons, or merely the basis of the demon myth and actually just from another dimension.
Everything we see of them implies they're not even on the level of mental development of jungle tribesman, yet your brain quite ironically can't wrap itself around the notion that creatures not of Earth being something other than super geniuses with advanced technology. You may as well be asking why gorillas don't use guns, or why lions don't domesticate their prey and keep them as cattle. That's how insanely idiotic your entire whinging about acidic water is.
You went back and checked, it was exactly like I said, so now you want to drop it.

Depending on your perspective, you could either say they overestimate the audience intelligence or didn't sufficiently clobber them over the head with the religious significance, but it's established her father is an ordained minister and that they say grace before they eat. The fact is, this is the only creature we actually see harmed by the water, and there's a throwaway line that other survivors were gathered at religious buildings.
It was every single different factor suggesting everything that happened was planned. His son having asthma, his brother being a baseball player, his wife's dying words, the daughter leaving the water everywhere. The creatures were clearly meant to be demons.
I wouldn't know, is becoming one your ultimate endgoal?
