How does it answer why consciousness or laws of nature exist? I included atoms as only one of the items on the list for a reason. Not to say science isn't useful or that it hasn't made progress in explaining things. But the line of thought that this question is related to is, loosely, whether there need be any ultimate, necessary explanation to things and what kind of explanation that would be, or whether explanations bottom out at brute, contingent facts. This kind of topic, regardless of whether your answer is a necessary existence or brute fact, doesn't seem to be scientific---or would you disagree?

> How does it answer why consciousness or laws of nature exist? That's a longer story than will fit in an HN comment. But the TL;DR is that once you have atoms, that leads to chemistry, which leads to biology, which leads to brains, which leads to consciousness and all the other interesting things that brains do. But these are all emergent phenomena. There's nothing brains do that cannot be explained in terms of atoms. > whether there need be any ultimate, necessary explanation to things and what kind of explanation that would be, or whether explanations bottom out at brute, contingent facts You're flirting with teleology here. There's nothing wrong with that. I'm making an observation here, not a value judgement. It is an open question whether there is an "ultimate, necessary explanation to things". But science can shed some light on that by demonstrating that if there is an "ultimate, necessary explanation to things" it almost certainly has nothing to do with us humans. We're just the result of rolling countless trillions of cosmic dice in one tiny corner of the multiverse. That's not the answer that most people who ask the question of "ultimate, necessary explanation to things" want to hear, but all the evidence points to that being the truth. And so the best explanation of people asking this question hoping for a different answer is that they are engaging in the same kind of wishful thinking as, say, erstwhile inventors of perpetual motion machines. Science can't prove that it's impossible to do an end-run around the laws of thermodynamics, but there is still a reason that perpetual motion is the canonical example of crackpottery.

  >There's nothing brains do that cannot be explained in terms of atoms. But the relationship between brain chemistry and consciousness is at best correlating certain conscious states with certain neurological states. The question is why there is consciousness at all. Maybe it's an emergent phenomena, sure, but it's not clear to me how the arising of consciousness from matter can be completely characterized through science. One reason is because science deals only with physical things, but consciousness is a non-physical thing. No doubt there is relevant science, but I don't know that science alone provides an explanation for why we are not philosophical zombies. You can, of course, take Dennett's view that qualia don't really exist, but in defending this view he did a lot of... philosophy. And QFT explaining laws of nature would be strange considering QFT is included in the laws of nature. >teleology Well, I'm not positing that there's any purpose or telos involved in these explanations, just that there are explanations---there are reasons why things are the way they are ("why" in the sense of material or efficient causes, not final causes). >It is an open question whether there is an "ultimate, necessary explanation to things".

Science can't prove that it's impossible to do an end-run around the laws of thermodynamics, but there is still a reason that perpetual motion is the canonical example of crackpottery. So my point here is simply related to your first sentence---there are philosophical arguments as to why there must be an ultimate, necessary explanation, and there are philosophical reasons to believe these arguments fail. But I don't see science as being sufficient for adjudicating this dispute, as I think you'd agree. (I would agree with your point about how science shows us just how small humanity is in the larger cosmos, though I'm not sure that's necessarily in contradiction with religion. But that's a whole other can of worms.)
