True, but that also requires you to assume that either a) the unspecified designer deliberately designed everything to look exactly as if it were the product of evolutionary development or b) this designer, in the face of astronomical odds, quite accidentally designed everything so that it looks exactly as if it were the product of evolutionary development.
Neither of those scenarios is unequivocally impossible, but neither has much going for it a a scientific theory. I mean, it's entirely possible we're all living in The Matrix too, and everything we are observing is computer-generated sensory input, but absence any sort of evidence to that effect, it's pretty much a scientific nonsatarter.
