Well that is the "hard problem", isn't it :-)

But your body is just a robot suit for replicating nucleic acids and you can follow an unbroken chain of those chemical reactions all the way to the first microbes. Which were still "optimizing for survival" without any intelligence beyond following chemical gradients.

If you say that means even microbes have some amount of qualia then I can't dispute it. Pure physicalism may necessitate panpsychism of some form.

Haha yeah, we're in "who knows" territory. It could just be a foundational truth that all life has an innate unconscious will to survive.

However, it makes more sense to me that consciousness precedes the will to survive. And that doesn't mean the way a microbe experiences life is the same as us. E.g. the fact that we have so much control over our environment might mean we have a much more sensitive and reactive way of engaging with consciousness, whereas maybe a microbe is like an enlightened monk, just chillin because it can't do much about what it experiences anyways.
