So if something cant be proved to be false, it cant be a valid 'scientific' hypothesis ?
You seem to be mixing up what this means. It doesn't mean you can prove something false, it means you can
test whether or not it is false. For instance:
If you drop a rock out of your hands, and it falls up, it means the theory of gravity is incorrect.
In other words, gravity is falsifiable, but not false. This is a really oversimplified example, but you see my point.
On the other hand, if I tell you that there are invisible, intangible gremlins that don't smell like anything or make any sounds living in the president's underwear, there is no way to test this hypothesis. It would amount to, "No, you've just got to trust me on this one." Therefore, this hypothesis is not falsifiable, and not a valid hypothesis.
