Yep.

How do you know that? (I know that it is a popular trope but familiarity is not evidence.)

I am interested in seeing the numbers and your calculations on this. How did you calculate/determine what a designer is “very likely” to do?

(1) Why not “reinvent the wheel”? (In other contexts we Christians like to say that God loves variety and creativity.)

(2) Does reinventing the wheel _require_ a reason? How do you know?

Isn’t it easier to accept the massive evidence for what ERVs are and do? Does parsimony provide any good reasons?
