...and other questions about Noah's flood for the layman. (posted @ atheistdave.wordpress.com)
What did the animals eat? Sure, Noah took two of every species on his ark. As if that's not believable enough, how did all the animals survive? Some animals have a very particular diet: they'll only eat certain plants, grasses, berries, or other animals.
What did the vegetarian animals eat? Did Noah also bring plants, trees, grass, nuts, fruits, and berries on the ark? Did he remember to bring eucalyptus for the koalas and bamboo for the pandas?
What about the carnivores? Surely an animal such as the lion would require more than two antelope to survive for five months. Speaking of that, why do we still have antelope if the lions ate them on the ark?
Did Noah also take fish on the ark with him? If not, why do we have such an abundance (80%-ish) of sea life on the planet? A worldwide flood that covered the tops of all the mountains would have severely offset the saline level in the ocean, killing all the saltwater species. Likewise, as the ocean's salt water and the land's fresh water met and mixed, all of the freshwater species would have died.
We would have a mass extinction of approximately 80% of all life on earth in the geologic record taking place only 6,000 years ago. This is not the case. We would have only very few (if any) species adapted to a strictly aquatic life. As the ocean is earth's most life-abundant biome, that is clearly also not the case.
Why are there trees? And grass, and bushes, and ferns? No plant could survive being drowned for five months (fact-check that if you'd like; there may be some that can - I'm no botanist). Unless Noah also included some of every type of vegetation on his cruise, a worldwide flood would have killed off all (or most) of the species of plant life on earth to the point of extinction. And yet in no time at all after the flood waters abated, a raven managed to find an olive tree in bloom. This would not have been the case. Six thousand years is not enough time for all the plant life on earth to re-evolve to where it is now.
Why is there still life? With all the plant life extinct, all of the vegetarian animals who relied on plants would then go the way of vegetation and sea-life, followed by the carnivores and finally, humans. We're talking about a global mass extinction here, consisting of 99% of all species on earth. You wouldn't be here, I wouldn't be here, the berries that became my coffee wouldn't be here, there wouldn't be a beautiful tree standing outside my window, and the lawn wouldn't be neatly trimmed.
