For the reason you mentioned. Since catastrophic floods are relatively common, it's not surprising that many diverse cultures have stories about them. And they don't seem remotely like the Noah story. The first example from AIG:
The Havasupai, another tribe inhabiting the Grand Canyon area, said that one girl survived the flood inside a hollow, floating tree, which is their version of the ark. “In this hollow tree he [God] placed food and other necessities, and also made a lookout window.”2
Oral traditions of the global flood from the continental United States are more prevalent than previously thought and confirm the truth of the Genesis account.

Wrong gender, no animals, no Ark or boat, no other people... The only thing in common is a flood.
