Your answer to the question: "where did the water go" is also non-sensical. if the water did not go anywhere and merely formed the current seas; then it implies that the water during the flood were the ones we know today. The flood was therefore not global and could not have drowned all of mankind.
If the water was so much lower before the flood, how come we only find underwater remain of human presence close to the actual shores? It is more consistent with limited changes in sea level through the ages?
6.5 meters? That wouldn't cover all the earth; many points would remain above sea level, once again, allowing for many people to survive.
How could the earth ecosystem work
before the flood? 6.5 meters of water canopy would
greatly the amount of light to make it to the ground to aliment photosynthesis...
How did the different species migrate to their final location? What did they eat on the way? One year of submersion would have killed all terrestrial plant life, devastating the ecosystem.
What exactly is the Biblical definition of kind?
You mention it being different from species (and much wider) yet give a definition as a 'population able to interbreed' which is the scientific definition.
Also, the Bible mentions several 'kind of Ravens' (Leviticus 11:13-19 ) suggesting a pretty narrow definition.
I know it is nothing but
post hoc rationalization to get around the 2 millions and some species, but still it is not consistent.
Anyway if, at the time of the deluge, there only one "kind" (whatever that means) for any major groups, that suggest that there only was one representative specimen for every major animal group.
But, if, as creationists generally argue, against all evidences of the contrary, the geological column was formed during the deluge, how could there be many different species of the same kind represented in the column? Like, a bunch of different cat species?
Why would these column show such an ordered progression between the fossils (you know, the evolution thingy)?
What would these fossil distribution be consistent between geological columns at different location? One would expect the columns to be but a chaotic mess of whoever sinks first.
How can these columns show such biogeography? How come that fossils from the same environment consistently be present in the same layer (for example, a coastal deposit would show layers of aquatic species, interespeced with coastal marches or terrestrial environments)?
If humans were present at the time, how come the human artifacts are only present on the topmost layers of the columns? You'd expect the denser metal artifact to actually think faster and get at the bottom of the layers?
Also, if all similar species "evolved" from a single pair of individuals, like in Creationists' version of evolution. That'd mean that, to give you an example, by 2700BCE, all cats were identical. Within a thousand or so years, however, we enough clear written and pictoral evidences that the lineage had splitted into clearly identifiable species (cats and lion had different pictograms, for example).
That means some kind of super-boosted evolution able to introduce such levels of divergence within a thousand years. Yet; we don't have anything nearly as drastic represented in the several times that period covered in recorded history (we have plenty of evidence of evolution, of course, just not as happening that fast).
How could Noah and his handful of family members construct such a grandiose wooden ship whose dimension
far exceed what is considered possible in naval engineering, even when they benefited from thousand of years of experience as well as very modern techniques and material that would have been unavailable to Noah himself (such as steel reinforcements)?
Especially considering the very rough condition that the ark would have had to wisthand.
Where did the pathogens go? Virus, parasites, several bacteria; they need a host to survive. A year interruption in their life cycle would have eradicated these species. Considering they are still around; they must have been present on the ark, which means that each individual on the ark must have had multiple infection, sometime quite serious ones, going on at the same time.
In fact; considering the short cycle of some of these parasites; there should have been either dead or cured (and hence no longer a carrier of the disease) within a short time (sometime a few days). When did the pathogen go in this case?
Seriously? Who of Noah's merry crew was responsible for carrying Ebola around?
that's just a few of the (not yet asked) questions that just popped through my head; I sure could think some more of them...
Also...
what this guy says.
