What Carl Sagan meant was that a theory must be the least complex one, give us experimental predictions which must be proven to be correct and yield the same results as previous experiments in order to be considered truthful. This means that a in the future new theories might debunk the ones we already have.

And their theories were abandoned overnight, weren't they? They weren't? I didn't think so. Now list all of the theories that scientists are still grasping tightly to and all of the subjects that serious scientists are afraid to study because it would tarnish their reputations since it would go against the dogma that the church of science believes in at this moment.

Oh, you meant that kind of "sacred truth". Its sad to admit it, but you're right -there's a lot of discrimination towards those who drift away from the accepted theories-.
