There are.

We can’t see magnetism. Or most of the electromagnetic spectrum.

We can’t hear too low frequency or too high frequency sounds.

We can’t perceive gravity (other than by its effect on our body), or the strong or weak nuclear forces.

There’s a flood of neutrinos constantly going through us without us noticing.

There are whole ecosystems of minuscule animals and bacteria living on and in us, which we can’t see.

We can’t even see the very air we’re breathing.
