It has always baffled me.
There really is no denying climate change at this point.
I think the reason they do is because they fear that admitting to climate change will lead to over regulation by the government. Just a guess.

The GOP are anti-climate change because they're idiots, or they are pandering to idiots.

That's a separate issue from evidence for gravity. You've shifted from wanting evidence of gravity to wanting a causal mechanism for gravity.
You might be arguing that gravity isn't a true force, which is true according to our best theory of gravity. But that wouldn't change the fact that there's some gravitational phenomenon.
So do you want it or not? None of this bs "show me what you think gravity means". Do you want evidence for gravity or not?
Are you projecting?You read up a little on gravity (probably back in high school) and you probably recently read up on logical fallacies, and you want to show the world that you read up on these two (at a very low level). But because what you read is at a low level, you got yourself into a quandary (and you don't even know it).
Just a few notes to add.
Quantum field theory doesn't include gravitation, but there are attempts to extend GR into some kind of quantum field theory. The other point is that not knowing why it happens doesn't mean that our theories of gravitation aren't good or that they have no explanatory power. Their predictive and explanatory power is excellent.
That we don't know everything about it doesn't mean we can't give informative answers, even to the question of why something falls.

The wording was bad on my part. What I meant to say was that even if gravity wasn't a real force, there's some kind of phenomenon that brings things together, and gravitation is just the label we give to this set of observations.
Yeah, it doesn't make much sense. TBH, I think everyone is struggling with climate change. What do we do?, What is going to happen?, What should we do?, etc, etc....
It is a problem we have never faced before, so it is understandable. There is no point in denying anymore really.
You mean, evidence like THINGS FALLING? What do you think that is, animal spirits?
BTW, you seem to have some difficulty with understanding just what a theory is. A theory is something that lets you make predictions in a large number of situations. That's it. The best theory of gravity we have, General Relativity, has successfully predicted what gravity does in every situation in which it's been tested. One cannot get a theory that's better than that (although future tests may make a better theory necessary, if its prediction don't work in some new situation.) There is no need (or, indeed, does it make any sense) for a theory to try to explain "why" something happens unless that's the best way to describe what the theory predicts.
It was a mistake of physicists in the 19th century to try to explain electromagnetism using mechanical models of an "ether". Eventually they became comfortable with just treating the equations as the theory and not demanding some sort of underlying mechanism.
There's a wikipedia page summarizing tests that have been conducted on GR.
