>Physical evident strongly supports the 13-ish billion year age. Radioactive decay shows that a young earth could not exist, as there would be lots of short-lived primordial radioactive isotopes.

Well, if one ascribes to this God thing, of course Earth could just as well be created 6000 years ago, with exactly the shape and vintage material properties to appear to us as it does now.

If you can create a baby Earth from nothing, you can also just create a middle-aged Earth from nothing.
