Does anyone else find it funny when "experts" think they know it all?

I see it and read it everyday. Just because your credentials state that you have a PhD in archaeology, biology, astrophysics, blah, blah, blah, doesn't mean you know it all. I just find it humorous when I get an atheist professor that can "scientifically prove" that we are all products of the "Big Bang" and "natural selection." I see this general attitude more and more everyday. Just because mankind has developed some high-tech devices doesn't mean we know it all. Like the news headlines read the other day, "It's official, an Asteroid Killed the Dinosaurs." LMAO! That could've been the case, but the "experts" say it's official now so it's a matter of fact.
