You're contradicting yourself. If they weren't an adequate approximation of a subset of Einstein's Laws for the reference frame of Earth, holding on to them as a low-cost computational approximations would be pointless.
Adequate engineering approximation would be a better way to characterize Newton's laws. They are not in any way a subset of Einstein's theory of general relativity.

(somewhere, some time ago, something happened, but whatever it was that happened wasn't evolution)
