> Are you describing Erich von Däniken's inability to change his mind when evidence clearly contradicted his theories?
Roughly 80% of the planet has an inability to change their mind regarding their religious beliefs.
In reality, there is more evidence of ancient aliens that there is of almost every other religion, and yet the people who follow religion aren't being vilified the way the ancient alien believers are.
I mean, look at your own question - do you routinely ask people (IRL and online) why they can't change their religion based on evidence?
I think you are quite correct to put Däniken in the corner of belief and religion, and not expect followers of his ideas to be open to rational argument by default.

What makes you think so? Most people don't really have strong religious beliefs that they are testing against evidence, I suspect. It's mostly just a way to connect with their communities for most people.
