However, new observations that agree with an explanation don't prove the explanation. Why not?
First, to prove a statement means to demonstrate that it is true with complete certainty, without any doubt. (Mathematicians, for example, use rigorous logic to prove abstract mathematical relationships, such as the Pythagorean Theorem.)
There are several reasons why new observations that agree with an explanation don't prove the explanation, and they have everything to do with degree of certainty. Here are a couple of important reasons:
