Pretty much this is by definition impossible; for example, Betrand Russell postulated a teapot orbiting the sun - how would you prove it wasn't there? Another example would be to claim that there was a grain of sand somewhere with your name engraved upon it; to prove that not true, one would have to examine every grain of sand in the world. To resolve this type of problem, philosophers invoke Occam's Razor - explanations should use the fewest number of assumptions.

You cannot prove a negative. This is a well known, well established facet of logic. In order to prove that something does not exist you go about trying to prove that they do exist and then report that you have failed. Having failed however isn't proof of non-existence, it is only a demonstration that it cannot be proven at this time.

Why can scientists never prove their findings?

This is a misnomer. Scientists often and do prove their findings, particularly through repetition of an experiment. Scientists cannot prove a negative (reindeer can't fly), but can only prove such under specific conditions (these reindeer can't fly in March). Theories are not said to be proven until they can fully explain a set of conditions. Even then, parts of a theory can be proven, but the whole remains open to refinement.
