"Unfortunately the rational means to recognize and wield certain self-evident biological facts are beyond the grasp of parrots who adorn themselves in vestigial Babylonian/Egyptian/Roman State-Established plumage whilst squawking from their pulpits that the world can’t possibly be more than a few thousand years old."

I'm sorry, I seem to have run into a reading comprehension difficulty. I'm not sure what this paragraph means.

In particular, who or what are these plumage-adorned parrots who squawk that the world can't be more than a few thousand years old?

Thanks...
