In fact, that business about the springs of water under the ocean provides a falsification of Genesis. The passage in question is Genesis 7

"In the six hundredth year of Noah’s life, in the second month, on the seventeenth day—on that day all the springs of the deep sea erupted, and the windows in the skies opened."
We can take the "windows in the sky" bit as a poetic expression meaning only that it rained a lot, but the reference seems clear that there was a source of water under the ocean, too. There is, however, no such thing: this is a reference to something in the Book of Genesis that is untrue.
Since the Book of Genesis contains an untruth, it cannot be regarded as authoritative, and we cannot assume that something is true merely because it appears therein.
As noted above, since this error is not part of the creation story, it does not invalidate the creation story directly, and it can still be true as far as this goes. However, we cannot assume it is true merely because it appears in the Bible.
