Here we go again, mocking the Bible.
For those that don't know, there were a variety of flood myths in that region that differ somewhat such as ancient Sumerian texts that have been unearthed. So what does that tell us? That tells us that there was a flood and that there were people who survived it to tell the world about it.
The only other option is, people made up the story about a flood without actually experiencing what a flood actually was. That would be like describing what an I-phone was back then without actually seeing one. That's right dingleberries, I'm calling you mocking Bible haters stupid. The Bible is a valuable historical document in a region where very little historical data has been saved and it should be valued as such. You may not agree with the account given, but to say there was no flood is just plain daft.
