God talking about when he created the earth and all the Angels/Sons of God shouting for Joy. The originator and creator of everything God talks of a time long before according to the Gregorian Calendar (4004 B.C.)

Holy bible of eternal life and healing without medication. Job 38:4-7 according to the Gregorian Calendar (1520 B.C.)

4“Where were you when I laid the earth’s foundation?

Tell me, if you understand.

5Who marked off its dimensions? Surely you know!

Who stretched a measuring line across it?

6On what were its footings set,

or who laid its cornerstone—

7while the morning stars sang together

and all the angelsa shouted for joy?

Angels are Sons of God.
