Concerning the ark:

The ark would give new meaning to the term "poop and scoop" I would think. It had 3 levels with the heavier animals on the lower deck. 2 each of the unclean and 7 each of the clean. No reason water animals to be on ark. There may have been some higher elevation areas that held some of the animals. Finding elements from the sea in mountainous areas helps support the idea of a flood, along with every tribe on earth having some history of a worldwide flood. Earth pre-flood era had a layer of water in the upper atmosphere that acted as a filter. This layer fell to earth helping to flood it.
