From the same wikipedia article:
> The most serious problem facing Milgrom's law is that it cannot eliminate the need for dark matter in all astrophysical systems: galaxy clusters show a residual mass discrepancy even when analyzed using MOND.[2] The fact that some form of unseen mass must exist in these systems detracts from the adequacy of MOND as a solution to the missing mass problem
MOND still requires dark matter to exist.

Thanks for linking that. That is very interesting that MOND needs dark matter to exist like that.
This article is the only one I could find that could "detect" dark matter and so far no one has been able to duplicate their results.
This article suggests that the best chance of detecting dark matter is currently in the middle of its 1000-day mission to collect data.
I honestly just need more than "trust me, it exists" before I can actually believe it because right now I laid out 5 questions that scientists can't really answer about Dark Matter.

This video is really good rundown of why astronomers are confident that dark matter exists even though they haven't directly detected it yet. The indirect evidence is overwhelming and can't be explained by any kind of ordinary matter or modifications to gravity. You're right that there are a lot of unanswered questions about dark matter - it's one of the biggest unsolved problems in science.
I recommend Dr Becky's channel in general for astronomy content. She's a PhD astrophysicist and great at explaining deep concepts in astronomy and cosmology
