I’m sorry that I did not limit my guess to the creation of the material world. Perhaps there are spiritual concerns which we are even less able to comphrehend.
Purification is often accomplished through burning.
In 2 Peter 3:10-14 is writing of a new earth and new heavens made suitable for righteousness.
I hope you keep searching for a better answer than I can give, rather than concluding that God blundered.
While I appreciate your sincerity, you completely miss the point of my post, which was directed to a Catholic.
The traditional Catholic teaching is that the final end of man is a "spiritual" paradise and that the material universe G-d created in the beginning will be annihilated. This is related to their belief in a purely "spiritual messiah" (a contradiction in terms) and their rejection of a literal King Messiah who presides over a literal messianic kingdom on this earth, which will at some future point be rejuvenated into "the world to come."
My question was purely rhetorical, demanding a defense of this "spiritualism," not because I was soliciting advice on what to believe.
