[Laissez-faire capitalist]

It was man's sin in the time of Noah that was disorderly and chaotic. Sin has brought havoc upon man even since Adam's time. The flood in Noah's time was judgement for sin. It restored order and swept away the sin of Genesis chapter 6 and the giants of that time.

[Raycpa]

The flood in Noah's time was judgement for sin.

So, God can use disorder and chaos in order to bring judgement. So, God can be the author of chaos so long as he is bringing judgement to his world.
