Now and before.

Actually dark matter has taken a setback recently among many top scientists.

Your link does not support this. Even the top result, which is a popular science article rather than an actual academic source, only talks about one specific possible explanation for dark matter not being particularly likely, not the theory of dark matter itself having any actual issues.

And, again, it wouldn't matter if it did, because the theories surrounding dark matter and dark energy are evidence-based. Even if they are eventually overturned, they are still evidence-based.

Theories about the existence of gods are not.
