Not a year, 10 months, and water started receding. And many ways a seed could have survived, even preserved in the carcass of an animal/bird/debris floating on the water.
Or God could have just made it happen, just as he did during creation. But believing that takes faith, which I assume you don’t hold.
If all it takes is faith to believe something happened, why go to such great lengths to come up with "incontrovertible proof"? Which is what this article suggests archeologists have done. I guess we'll find out in 2 weeks. 😆
