The alien UFO folks have cried "Wolf!" so often it's going to take concrete evidence.
We've seen so many claims by so many people which have turned out to be false, wrong, hoaxes, or only misinterpreted that the UFO folks have no credibility. Only a fool would believe the next weak claim based on tortured data which can be interpreted as possibly indicating aliens - if the first million weren't accurate the next one is liable to be in error, too.
Sorry, but it's going to take something quite substantial, in fact a few things which are quite substantial, in order for the UFO idea to gain credibility.
