Well, ofcourse it is possible. But what you have got to ask yourself: Is it probable? Is there any evidence that there was a few thousands of years
ago a catastrophe so large that it would kill all the animals and humans, while leaving all plants unharmed? Why haven't we found one layer in our
geological layers with remains of thousands of killed animals and some evidence of this huge catastrophe? Considering all this, I don't think that
happened.
In my opinion the story of Noah's ark is either a legend of a some flood in a small part of the world that has changed a lot over the years before
this was written down or it was made up entirely.
