We sense what our senses allow us to sense

Of course it is sort of difficult to conceive space and time without our senses. Space exists because there are bodies in it. Where come our senses from? Well, we are more or less convinced that it is through evolution: we don't thing microbes have senses that allow them to "feel" space and time. On the other hand may be there is much more in the universe that sounds, bodies, tastes, smells, colors and what we translate to our senses by means of the instruments we have invented: the full electromagnetic spectrum, the far away galaxies, some evidence of black holes, and so forth. Who tells us this is all the universe? Who tells us there are no other ways to sense or to conceive the universe?
