Intelligent interstellar aliens using unfathomable technology, secretly interacting with humans doesn’t.
What you’re asserting at this point is that all of science as we know it is wrong, and everything we’ve built was just incredible, one-in-a-trillion fortune that any of it worked at all.
It’s like looking at a plane or a helium balloon and deciding gravity is wrong.
That’s not how revision in science works.
We know that Newtonian mechanics was wrong and incomplete, but at the same time, it didn’t work by “luck” either.
I’m not a physicist, but I am mathematically literate, so please feel free to direct me to technical sources.
And the problem with just being okay with our wrongness is that it doesn’t match up with our ability to predict and rely on the science to complete complex engineering projects.
Here’s a math example: it’s like saying 1+1 is sometimes actually fleeb. Easy to imagine, but wholly destructive to the entire concept of math.
But a theory can be false while still being predictively accurate.
Classical mechanics predicts that quantum tunneling should be impossible. But as it turns out, quantum tunneling is possible. So classical mechanics is false - or at least partially false. But classical mechanics is still predictively successful in a wide range of scenarios. So, a theory can be both false and predictively successful.
The most natural way to explain this is to say that classical mechanics is an approximation of a deeper, more accurate theory. Similarly, our current best theories could be approximations of as yet unknown theories - theories that allow for certain phenomena that are currently thought to be impossible.
There is likely an LK-99 sized gap in scientific knowledge, there is not likely an “aliens land on earth and want to hang out” sized gap.

On the UFO side it's mostly hucksters and numpties commenting "wake up sheeple, you can see it's CGI" on ISS live stream videos.
I said this was like pulling teeth. Sheesh.
Spoilers: it's not Atlanteans either, it's just a big tangle of hoaxes and self-delusion from people who want to believe.
Exoplanets weren’t confirmed to exist until 1992. Just sayin’.
The main argument in favour of the non-existence of aliens are religious books.
Not in the slightest, that's the worst strawman against it (and for the record, I am an atheist, so drop this line of argument now before I'm forced to counter-insult you.) Try the Rare Earth Hypothesis. There are only 10^11 stars in the Milky Way galaxy, you don't need to stack up many terms in a "Drake equation" to push the result to near zero in the Milky Way. The Rare Earth Hypothesis is consistent with all empirical observations thusfar.
Furthermore, even if there were other intelligence species like us in our Galaxy, they would be incapable of reaching us just as we are incapable of reaching them. To believe these aliens are visiting Earth you need to explain why you can't see them anywhere except ostensibly in deserts above American military facilities and installations for testing secret aircraft.
FWIW, I think this is a much stronger argument against the existence of aliens than “they don’t fit with our current understanding of physics (which is known to be incomplete anyway)”.
Unless they took a completely different, or radically faster pathway to interstellar travel.
These are pictures of exoplanets made in 2022.
I doubt we really know what is going there.
The best we can do is to guess the chemistry of the atmosphere and assume that all forms of lives require the same setup as on Earth.
