A lot of people seem to think that, just because they don't know something, that means nobody knows or even that it is unknowable.  This is common among people who aren't very well educated because almost everything is an unknown unknown to them.

Or when they don't know something, they just make something up because they have an ego problem where not knowing = stupid. I respect the person that asks questions more than the person who acts like they know what they're talking about with no basis.
