Well, if you look away from the unproductive ideas that nothing can ever be proven yadda yadda, obviously we do find some objective truths despite us to a large degree relying on our perceptions.
For example, you can percieve the colour blue. Yet, we know from studies that blue is actually electro magnetic radiation with a frequency which is within a certain spectrum (~440–490 nm). That's not something you'd know from looking at a blue car, but we can still figure it out.
