If Noah's flood were just a local flood, then God is a liar.
"I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth. Whenever I bring clouds over the earth and the rainbow appears in the clouds, I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life." Genesis 9:13-15
We see devistating floods all the time. We see pictures from around the world showing homes, streets, entire towns underwater. Now if God set a rainbow as a sign of His promise that He would never again do what he just had done, then he broke His promise.
