[Standard] Testability [Why it's important] 
Just in case a person making a claim isn't simply lying or incorrect for some reason, testability gives us the ability to verify each others' claims. Until a claim is tested, it's simply an assertion. How does one test the assertion that the birds and trees are evidence for creation? Not everything has to be directly observable or testable. Like magnetism that we cannot detect with any senses, we can investigate it indirectly, with metal objects for instance. Evolution makes testable claims. It can be used to predict that at one point, water creatures evolved into land creatures, and we could potentially find transitional forms of when some did evolve. This was successfully tested when we discovered Tiktaalik, as predicted.
