There's a reason most people see the ark story as non-literal; it's entirely impossible with any size boat.
That's not true. You could theoretically build a boat capable of hosting two instances of every living species, it would just be the largest boat ever made and would be a completely impractical waste of resources that would most likely end up sinking anyway.
Nah. It was just the ancient technological equivalent of a thumb drive (probably based on mysterious crystal energy!) containing a comprehensive dna database.
Though even in that case, it still wouldn't work; as the mandate requires '2 of each kind;' but without any rigorous, scientific meaning of 'kind' that becomes muddled and entirely unworkable. Even the well defined, modern notion of 'species' breaks down fairly quickly, as there is no real dividing line between one and the next.
And then there are some slight requirements for a habitable biosphere which are overlooked... like habitats. 'what do we do with these bark-beetles now that all the trees are dead and we weren't told to take any?' 'ah, just put it in the stew with the others...'
Quite the incompetent planning all around, really. Then again, the whole plan
is the result of said planner-deity saying 'ah, shit, I need a do-over.' A do-over which happened to involve genociding nearly all of everything. A do-over which the planner-deity thought was required because, after giving a creation free-will to do what they wanted, they did something other than what planner-deity wanted them to do. By excersizing their free will. >_>
I wouldn't trust this deity to be competent enough to hire it for a job as a Walmart temp-worker...
