God essentially said what he told Habbakuk
1:5 Behold ye among the heathen, and regard, and wonder marvelously: for I will work a work in your days which ye will not believe, though it be told you.
Quoting: Anonymous Coward 78042523 God unsurprisingly has already formulated a plan and lays it out for Uriel to follow:
Enoch 10:1 Then the Most High, the Great and Holy One spoke,
2 And sent Uriel to the son of Lamech {Noah},
3 Saying, Say to him in my name, Conceal yourself.
4 Then explain to him the consummation which is about to take place; for all the earth shall perish; the waters of a deluge shall come over the whole earth, and all things which are in it shall be destroyed.
5 And now teach him how he may escape, and how his seed may remain in all the earth.
