There is enough evidence out there. You are choosing to ignore it.
Oh yeah, the "evidence" that every time anybody any where sees something they don't recognize it's a demon. That's not evidence of anything except the terrible dearth of rational thought of the populace as a whole.
Going back to the hospitals, perhaps cancer was a bad analogy.
The fact that you saw it as comparable speaks volumes. Lessee, evidence of a disease that kills mllions vs. evidence of aliens (demonic or otherwise) who nobody has ever demonstrably seen, heard or interacted with in any way. Apparently the magnitude of the difference is lost on you.
"Ah, but abductees!" What about them? Last night Robert E. Lee dragged me out of my bed, forced me to go with him to Gettysburg PA in 1864 to explain what he really mean to do there, took me back to my house, stayed for a cup of coffee, and then disappeared. I awoke 3 hours later, AND THERE WERE TWO EMPTY COFFEE CUPS ON THE KITCHEN TABLE! THERE'S YOUR PROOF!
Covid would have been a better one because you have people denying the virus is real, hospitals are lying about people overwhelming them (ie in reality they are empty) and it's all a ploy to get people to take a nano-particle vaccine so people can have mind-control, etc..... People believe this UNTIL they or someone close to them got infected and then later got very sick, died or got long-covid.
The virus deniers are more closely akin to the UFO buffs than otherwise. They denied the evidence of people dying around them because it didn't fit their narrative. They had to deny the virus because their faith depended on it. UFOloonies deny the dearth of evidence that aliens (demonic or otherwise) exist at all, because it doesn't fit their narrative. They insist on the existence of aliens of whatever kind because their faith depends on it.
I'm a firm believer in the law of parsimony: a principle according to which an explanation of a thing or event is made with the fewest possible assumptions. In other words, the simplest answer is the most likely correct. During the pandemic, I accepted the existence of the virus because I could see the evidence all around me. Deniers had to build a complex web of conspiracies and cabals and what have you to explain the virus they didn't believe was there. One view was parsimonious, one was not. One was obvious, and one was not. In the words of the Prophet Mohammed,"Duh!"
Same with the idiot "wet market" notion of the origin of the virus. One view said that Chinese people eat bats, because strange foreign people will eat bats (I never knew a Chinese person you could throw a bat and hit with it, much less get him to eat one), and that Covid 19 had by some coincidence jumped from bats to people because old Mrs. Chen had bought a bat and cooked it and then everyone who'd had supper with her caught the disease and thus a pandemic was born.
OR... THERE WAS AN ACCIDENT DOWN THE STREET AT THE VIRUS WORKS, A VIRUS THEY WERE WORKING ON GOT OUT, HENCE THE PANDEMIC!
One of those is parsimonious, one is not. Your choice.
So, you see a flying thing, you don't recognize it, so it's probably either: A) a boring workaday flying thing that for whatever reason you couldn't make out properly, or B) a demon attempting to pass himself off as an alien from outer space so as to deceive you into believing that aliens exist so that you will abandon your Christian faith and replace it with alien worship or something we're not sure what. WHICH EXPLANATION IS PARSIMONIOUS?
However, I think the best evidence is the ancient structures, such as Pyramids (not just in Egypt, but in Peru and other parts of Latin America), or ruins where the stones are carved in such a precision and are so heavy to quarry and carry to another location that even modern equipment and machinery can't even do that would point to signs, that the world as we know it is not easily defined. You can't hide the fact these structures exist in the first place or that that are impossible to construct in the modern age, let alone with people using stones and sticks.
OK, so the pyramids and such were either made by:A) aliens, B) demons trying to make believe they're aliens, or C) people pretty much like us who knew how to make the best of the resources they had at the time. Which of those choices is parsimonious? I think I can predict your answer.
BTW, yes, we could build the pyramids today, if anyone was inclined to do so given the time, money, and resources it would require, which no one is.
