Science goes where the evidence leads. The theories are better because they are based on evidence, nothing else. If the predictions from the theories prove true, then the theory holds. That is the ultimate test. If the predictions are all true, then the the theory is right as far as the natural world is concerned.

The idea that anything is possible is comforting. If you want to believe that, that's your prerogative. But any theory you give serious consideration should be based on the facts, and any superfluous postulates should be removed.

There is an absolute right or wrong. While we may have no way of absolutely ascertaining what is right or wrong, I contend that it is far more absurd to assert a conjecture with no evidence than to assert one backed by evidence.
