Yes.

Accepting these facts is one thing but "getting over the astonishment" never happens for me.

I mean, your brain has an order of magnitude more neurons than there are people on the planet. I think humans are just incapable of wrapping our heads around the sheer number of tiny things that fit in small macroscopic spaces.
