Evidently, the God of the Bible is not above making mistakes (c.f., the whole Noah thingy).
And even before that, the oopsie with the snake and fruit tree. The whole thing went awry within days of the very start, so He had to reshuffle the rules and try again.
Then the Noah thing, the Tower of Babel thing, the Red Sea intervention because He didn't have a road where it was needed, the scrapping of the Leviticus rules, not to mention the release of the V2.0 Testament later on, etc. etc.
Seems pretty hands-on tinkering to me.
Could have been just noodling around with the universe.
