Does The Flood Add up?

the flood, as a local event, is no less well supported than the myriad other flood stories (almost if not every culture has one). however, outside of recalling the 'waters' upon the earth and exampling the threat of returning the world to how it began (hmm possibly a collapsed then re-expanded universe *ponders*) which was then one again established, a global flood as a recent phenomena is utter daydream. but then this requires the acceptance of modern science, which tends to be a problem.
