Does the Genesis creation narrative require that God created the earth's moon complete with at least some of its circular pock marks and impact-appearing scattered rock fragments (i.e., "mature" in that sense) otherwise often explained as evidence of meteor impacts (that is, a process subsequent to origins)? Does the Genesis creation narrative require what appears in telescopes as an exploded star (with high temperature objects and light radiating out from a geometric center) was created originally in what appears as in star-exploded state, complete with light radiating out from the objects at distances that would normally take billions of years for light to travel, in this case to earth for us to observe?
The question is not, "Can God do such things?" or "Can God make something initially in a way that appears to have a natural causative process before such origins? I think we agree God can, technically speaking. Rather the question is "Did He?" (per Genesis 1) or "Did He in some sufficient number of ways create in such a way as to imply some natural process before origins without such processes having occurred? Or otherwise, would you further explain what you mean, aside from the example of Adam, by creation with apparent age when human observation suggests natural process prior to proposed origins? I think it would clarify best by sticking to cases of origins of the material universe other than those involving living organisms or beings.
Or in other words, I'm not sure where this argument you are making is headed or how to weigh it. In my former post on this thread I have offered an alternative explanation to reading Genesis 1, though from one "relativity" vantage point the days are also literal 24 hour periods, which seems to alleviate the challenge here in its own way, but "apparent age" may have merit provided it can be better qualified and vetted--unless that would better be done on a separate thread.
