One more thing among many that YECs don’t recognize in their claiming that evolution is a conspiracy among biologists is that all of physics must be conspiratorial, too.
The so-called (by YECs) ‘secular’ hard sciences* all concur and attest to the antiquity of the universe. They share much of the mathematics, measuring tools and techniques and technologies, and these are the same sciences that put men on the moon. (They also brought us the atomic and hydrogen bombs. Feel free to argue with THEM. 
)
The physical and earth hard sciences and their subcategories that ALL attest to the antiquity of the earth and the universe would have all advanced to where they are today even if the concept of biological evolution had never been dreamt of, or even if the life sciences did not exist.
