The model might incomplete: do you have actual evidence that disproves it?

Is is a poor precedent, very bad astronomy.

Unless you provide some better theory, you have no reason to throw it away.
The validity of any theory has absolutely nothing whatsoever to do with whether or not there is a competing theory! That is a fallacy. You throw away a theory when it has been nullified – proven to be incorrect. But if you bend the rules of science to prevent nullification of a theory, you have transformed what may have once been a scientific theory into a cult.
