Absolute certainty is a luxury which the poorly educated can indulge in to excess.
Oh i assure you well educated people indulge in supposed absolute certainty also, or they believe their own bullshit or just want others to think so or have you never watched political news?
I'm annoyed when non-believers (who I expect to know-better, silly me) say "science proves". Science can disprove, but can't prove anything (it can be convincing). I agree, absolute certainty likely doesn't exist.
