[Raycpa]

11In the six hundredth year of Noah’s life, on the seventeenth day of the second month—on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened.

[The Theophilus]

"...and the floodgates of the heavens were opened."

I'll do you one better. In Genesis 1:2, we know that the earth was formless and void and covered in water. On the fourth day, God created the heavenly objects. The take away from this is that the Earth is the oldest thing in the Universe (by only four days) so the oldest water in the Universe is what I'm drinking right now.
