Is everyone in Texas an idiot or just you?
There are idiots in every state. Seeing as how I live in California, it would be hard for me to speculate the idiot to non-idiot ratio in Texas.
I know here in California the idiots seem to have us vastly outnumbered.
That being said, I'll take your answer as a, "Yes. These researchers are scientists."
I congratulate them on their ability to admit what they've thought about the age of the Andes was wrong.
It'll take some time, but I'm sure they'll come to the same conclusion about evolution, global warming, Pluto, etc.
