ELI5: Why don't bugs take fall damage?

I've seen bugs fall from high distances yet they walk away fine, why is that?

Two main reasons: First, they're very light. The force of an impact is proportional to the mass of the object involved. Insects have very little mass, so they receive comparatively little force. It also means they have a low terminal velocity because the force of gravity pulling them down is more easily countered by air resistance.

Second, they're armored. That doesn't seem consequential when you squish a bug, but on insect-scale the exoskeleton is quite strong, and it helps them minimize the impact of what force they do take from falling.
