I am not sure if consciousness is something that has to be “explained”.
With matter, you go deeper and deeper, until you have the smallest material particle. There is no “explanation” needed for this last particle. It just is. Consciousness is like the smallest material particle that we have. It just is. There is no need to “explain” it.
What science should do is to explore the way consciousness causes physical entities to change (none has been discovered so far) and the way that physical entites cause consciousness to change \ how it creates it. The question is how two different existing things interact (or how one of them creates the other), not about explaining one in terms of the other.
If that didn’t answer I would be glad to know what is missing.
Where we disagree is that they are “two different existing things”. We’ve just boiled all this down to the traditional argument over dualism. I’m unmoved but I do thank you for your time, effort, and patience.
