THEN it is INDISTINGUISHABLE from there not being any.
That assumes we’re the end all be all in terms of knowledge
It doesn't assume anything. Our knowledge IS the end all be all of our knowledge necessarily.
IF there is some knowledge or truth or fact that we don't have access to THEN it is exactly the same for us as if there is no such knowledge.
How does that help?
and there’s another side I argued that you’re not addressing and that’s nihilism.
IF none of us is a nihilist BUT nihilism is "correct" THEN .. what? What exactly are we to conclude from this?
ANY GIVEN POSSIBLE ANSWERS are not necessarily CORRECT ANSWERS.
It is IF it’s in the form of a greater meaning.
Ok IF there is some greater meaning but we don't have any way to assess it or even determine it exists THEN ???
All the answers we do have come from rigorous application of the scientific method and science does not address WHY only HOW.
In that case if there’s no why then there’s no sense in caring.
We observably care even if there is no sense in it. So...
IF there is no sense in caring and IF humans still care about (some) things THEN ???
we have defacto agreed that there isn't any objective meaning.
No, just because I don’t argue in favor of something that doesn’t mean I’m not in favor of it.
Sorry but what does that even mean in practical terms? I mean do you even understand why the nul hypothesis is useful in logic?
If you believe in every proposition that cannot be disproved then you will start to believe all sorts of discordant and contradictory nonsense. For example
IF you believe in objective morality BECAUSE it cannot be disproved THEN you must in order to be consistent in your methodology also believe in the flying spaghetti monster* BECAUSE it cannot be disproved.
That is why you don't have to necessarily make the positive claim that something doesn't exists to dismiss it. On the other hand we don't just assume the existence of things we can't demonstrate especially if they aren't even being argued for.
