If we're being generous, we can interprete Genesis 6:19 to mean that Noah was to bring two of every general type of animal that's worth giving a colloquial name onto the ark, and keep the species going for the duration of the flood. So for example, Tigers and lions would be counted separately, but eastern gray squirrels and red squirrels would both be covered under "squirrel". This task would've been theoretically possible, but realistically highly improbable. Noah, a random Jew from millennia ago, would have needed to not only travel the entire world, from the Galapagos to the South Pole, finding animals that the rest of humanity wasn't able to discover until roughly 6000 years later, but was also capable of getting all of them to come onto the ark itself without issue.
Of course, the Bible does not specify that they need to be land vertebrates. Certain prominent translations specify flesh, which implies vertebrates, but that's it. If we expand it to include non-land vertebrates, we've gone from highly improbable to outright impossible. Noah would needed to have needed to be capable of 1. deep sea travel, 2. bringing deep-sea fish to the surface unharmed, and 3. creating an environment that these fish are able to live in on the ark.
