There isn't any evidence that there is anything happening that's not biological despite 1000's of years of searching for that evidence.
And there is all kinds of evidence that biological processes can explain our experience. More all the time.
It's not definitive in the sense that we're anywhere near completely understanding our biology.
But it's the most likely explanation, given what we do know, but such a huge margin that there is no real alternative explanation outside of mythology.

Do you consider software in a computer to be mechanical? You could record the 1010101 in an electricity stream and conclude there is no meaning to that electricity beyond getting from point A to point B in a chip.
If we're looking for something supernatural like a soul, then we shouldn't expect to see natural evidence. Thus the lack of that evidence does not imply its nonexistence. Relevant xkcd: https://www.xkcd.com/638/
Sure you can say that our lack of evidence means nothing since we don't have the capability, through natural laws, to acquire that evidence.
But that's just another way of justifying faith as a rational argument.
The only reason we have to believe in the supernatural is mythology. And the only reason we have to believe mythology is faith (and fear).
yes but it didn't.
see how silly that sounds.
so on one level sure you're right, on the other hand it's obvious. no, there's obviously no super transparent cord going off to soul land. it's just a bunch of sell-contained cells. It's not wireless. It's not even networked. It's just limited to within your body. You can literally plunge yourself in water and still think.
you have no cord going off into ether. you are nnot a networked component. you are just a bunch of cells in one little package and that's it. That's you. your output is what your body does robotically (move, make sounds) your input is sensory. and your consciousnes is whatever your braincells are doing.
> there's obviously no super transparent cord going off to soul land.
You make it sounds extra silly by using this type of language. Remember when hardcore scientists were saying "my dear you must be mad to think the earth is round", or "yeah OBVIOUSLY the stars are pinned to crystal spheres, they can't just fly, that would be silly".
Anyway, the only thing we can be sure of is that we just don't know. Everything else is simply stories we tell ourselves to make us feel better. We play little games, but not all games offer the same experiences.
what do you think the chances are of finding a small metaphysical soul organ in the brain, that connects us to the ether where all the real consciousness happens, is?
Give a percentage chance of that happening.

okay so now what are the chances that I'm God and really just said that? If you said anything over 0.00000000% you're totally wrong. There is no chance of that because it's stupid. the above paragraph is obviously satire, because it's stupid.
You are presuming that the physical is all there is to existence. You fail to consider the possibility that there are portions of reality that we don't have the physical capability to perceive or the mental capability to truly understand.
There's a difference between saying "there is no evidence of X" versus "there is no evidence of X, so X is impossible"
I estimate 0.00000000%. What's your estimate?
I feel that consciousness itself is something non-physical. Whether it be a specific cocktail of neurotransmitters working in concert to give us the characteristics that we attribute to sentience, or a "core" form of existence that exists outside of our physical existence, I don't know, and I don't presume to know. I also don't presume I should be going around and acting like I can say with complete authority and accuracy "X doesn't exist in any way, shape, or form, because there is no evidence". I mean, what of the many other "scientific facts" humans have revised and subsequently rejected over a few millennia?
What if your base assumptions are flawed ? The current materialistic approach is based on flawed 15th century intuitions. Just like the previous assumptions were based on other flawed intuitions (gold can be made from any element, stars are on crystal spheres, earth is the center of the universe, &c.)
What makes you think our current assumptions are the absolute truth ?
