But it is remarkable that nature was put together in such a way that it is possible to learn so much about seemingly impossible-to-know things. Not that we're anywhere close to 'knowing' everything there is to know, as if that were even conceivable.
I don't feel the slightest amount of humility about man's ability to pick apart the mysteries of the physical universe. Frankly, I'm continually amazed by it. Our capacity for learning, deduction, analysis, cognition, intuition, realization, imagination, etc., is actually pretty astonishing.
We've even gone a long way toward picking apart the mysteries of our own existence, though admittedly, that aspect of our learning lags behind our discoveries in the physical realm.
If we can somehow hold on long enough for discoveries in the mental/spiritual realm to enable us to overcome our brutish, animalistic tendencies, we will conquer the stars. I truly hope that we make it this time.
