Science may be the term used to describe the human's observation and understanding of his surroundings. But what he observes and understand, the Laws of the Universe and its matter, would still be even if we didn't witness anything for whatever reason. Particles would still compose matter, planets would still circle around the sun, light would still travel at 299 792 458 m/s , and stars would still implode supernova style.
Indeed, when put against everything that we have yet to discover about the universe, we know next to nothing. But saying that we know nothing because it's all based on oh so flawed human observations and sensitivities does in no way mean that our observations and knowledge are wrong in and by themselves. We may have created our own language to describe what we observe, but that doesn't change what we do observe.
The means by and with which we do observe and understand the things that surrounds us do improve over time and we do correct ourselves if we didn't fully grasp the phenomenons at first, or if we plainly made a mistake or miscalculation. But all that it mean is that our knowledge is incomplete, not non-existent.
Take the recent discovery of the Higgs boson at the CERN's LHC. It may or may not be proven to be the standard model's famous missing particle once more exhaustive tests and studies have been conducted. But the fact still remains that a new particle was found and oberved in last July. We now know it exists. We're just not yet sure if it is exactly what we think it is.
