First of all, thank you for the beautiful and thoughtful reply.
I agree that there are unknowns everywhere, but I don't know enough to know if they are truly unknowable. I hope that makes sense! Maybe we will know them in the future. Maybe someone besides me already knows them.
I agree that we can have experiences, especially in domains where our knowledge is extremely limited, that can make us question whether empiricism is all there is. That's good! I like to question things I thought were true to test if I was wrong. But to take the invitation to question as an answer seems a bit premature. If empiricism isn't all there is, how can we know that? What does "knowledge" even mean, then?
In closing, I resonate strongly with your James Taylor quote. (Aside: I just learned "Fire and Rain" and it's a fun tune on the guitar!) I am enjoying the ride, and I'm glad you are, too! My disbelief in deities or the supernatural doesn't remove the wonder from my life. It helps me appreciate how much we don't know, but also marvel at how much we do!
