Many of the verses imply that the Flood was not regional, and had covered the whole globe, destroying all the living creatures. To this effect all the races of mankind now living on earth take their origin from either one of Noah's three sons, namely HAAMM-SAAMM and YAAFTH. The above verses too, denote that Noah embarked one couple of each animal species which may imply that the Flood could have killed all the living creatures; and yet Allah knows better whether the Flood was a regional or a universal, because the same reason can be used to prove both cases.
