God promised Never to Destroy the Earth with a Flood Again

Genesis 9
verse 11 tells us "I establish my covenant with you: never again will all life be cut off by the waters of a flood; never again will there be a flood to destroy the earth."
vs. 12 "And God said, This is the sign of the covenant I am making between me and you and every living creature with you,a covenant for all future generations to come:"
vs. 13 "I have set my rainbow in the clouds,and it will be the sign of the covenant between me and the earth."
vs. 14 "Whenever I bring clouds over the earth and the rainbow appears in the clouds,"
vs. 15 "I will remember my covenant between me and you all living creatures of every kind. Never again will the waters become a flood to destroy all life."
vs. 16 "Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all living creatures of all kind on the earth."
vs. 17 "So God said to Noah, This is the sign of the covenant I have established between me and all life on the earth."
* God promised never to destroy the earth and its inhabitants with a flood again!
*Proves all the more that it was a universal flood,not a local flood.
