IMO, this kind of amazement mostly points to humans not really unserstanding how tiny the building blocks of reality are. Even the "massive" protein molecules your body uses with hundreds of thousands of atoms in them, tens of thousands of amino acid chains, can fit many on the tip of a sewing needle.
Titin has over 30,000 amino acids in it, and barely gets over 1um in length. That's barely wider than a sharp razor blade's edge, and they're orders of magnitude sharper than most knives.
The scale of the world is crazy, and we are already giants in it.
