@Naa even falsifiable theories are subject to opinion. Is a theory falsified or merely incomplete can not really be answered for sure

The standard model of cosmology is a great example. No one has found any proof that dark matter or dark energy exist, yet the theory isn't abandoned but adjusted to fit experiment. I'm not sure if it is any more than curve fitting the data...

Not an astronomer obviously but I'd say there's plenty of evidence for the *existence* of dark matter. It's the theories regarding most of it's other properties that currently lack supporting data. Also, in physics there are no "proofs". Just extremely high confidence.

Well there isn't even evidence, I'd gladly settle for that. At higher and higher energies, it becomes less and less likely that the theory is right

What? There is plenty of observational evidence for dark matter. (And plenty that dismiss alternative explanations such as modified gravity.) However, re the OP I completely fail to see how that's a non-scientific problem. I'd say it's a very scientific one.

The point was that there is plenty of disagreement over scientific problems, and that even scientists disagree

Sure. But that doesn't mean that science as a method doesn't work. On the contrary: It provides a framework to refine and advance our understanding of the Cosmos. That includes that we sometimes find out a previous theory was incomplete.

Out of curiosity I'd be interested in evidence of dark matter if there is something I missed(probably plenty)

The classics are rotations of galaxies and gravitational lensing. Both suggest that there's more matter (causing gravity) in galaxies than can be explained otherwise. 1/

That's experiment, is dark matter really the only explanation?

There are other theories, the most promising one is modified gravity afaik, but they don't match the observations as well as dark matter.
