I don't think anyone is claiming that science isn't biased because it's conducted by humans. Just like I don't think anyone is really claiming that the OP is incorrect in their statement. The comments I've read are merely pointing out "X causes Y does not mean that Y implies X" is a given in the context of a scientific discussion. It reads as if you and the OP are getting wrapped around the axle by treating science as an outcome rather than a process and, in doing so, fighting a claim that was never made, and one where the counterclaim is generally well understood in the scientific community. So well understood that it doesn't really need to be said.
I've not made any claims that science is the only path to truth. But we are talking in the context of scientific domains of physics and cosmology, so using science as a benchmark is probably apt. If you want to discuss philosophy, that's all well and good but probably more appropriate for a different thread.
And I'll help you: I acknowledge there is plenty of room for error on my behalf. I also acknowledge there is probably plenty of value in things that can't be measured by science, but I'm not sure they belong in the topic of physics or cosmology. However, I don't think the wordsmithing is the way to illuminate error in the context of this discussion. It seems to fall into the realm of modern philosophy that is more about arguing words in the vein of trying to be smart, instead of good.
