There is evidence of several floods, but not a global flood which is impossible. Where would the water come from to rise up enough to cover all land?<quoted text>
Global flood is first recorded in the Vedas and thereafter in other cultures.
There's no geological evidence to support the same and it is illogical to speak of taking on board the ship single pairs of the tens of millions of species including aquatic and aerial and subterranean forms that were then present and it is silly to assume that these individual pairs restart life after the flood which would result in incest of the worst kind that would wipe out or retard the subsequent generations.
The global flood myth is a mystical event as narrated in my previous post on the subject.
There was a flood when the Mediterranean broke through at the Bosporous to fill the Black Sea, hitherto a freshwater lake.
There were others when ice dams broke at the end of the last glacial period. This occurred in North America as well as Siberia.
