I'm sure they are good at what they do, but would you honestly want them working in other scientific fields where the age of the cosmos is important? How do they justify a young Earth while working with elements that have provably been around for millions of years?
Like Kirkwood pointed out earlier, if someone believes the universe is only 6,000 years old, how do they explain stars that are millions of light years away? They obviously wouldn't cut it in the field of astronomy.
The one guy I have in mind in particular is a man of great technical understanding.
I'm just saying.
