As long as I duped, I'll try to make it useful.
Estimates show that it would have taken 20-30K people 20 or so years to build the great pyramid at Giza. The tower of Babel could have been no less of an undertaking, and would have been around 150 or so years after the flood.
How do you go from 8 to 20K in 150 years?
There are also between 1 to 100 million different species of beetle:
Wikipedia
Coleoptera ( /koʊliːˈɒptərə/) is an order of insects commonly called beetles. The word "coleoptera" is from the Greek κολεός, koleos, "sheath"; and πτερόν, pteron, "wing", thus "sheathed wing". Coleoptera contains more species than any other order, constituting almost 25% of all known life-forms. About 40% of all described insect species are beetles (about 400,000 species), and new species are discovered frequently. Some estimates put the total number of species, described and undescribed, at as high as 100 million, but 1 million is a more accepted figure. The largest taxonomic family, the Curculionidae (the weevils or snout beetles), also belongs to this order.
Taking the current known species of beetles, 400K, how do you fit 400K pairs of beetles into the ark, and their associated food requirements along with the 5000 pairs of the known frog species? Perhaps the better question is how do you round up pairs of the 400k species of beetles to get them onto the ark in the first place?
Was the ark some kind of extradimensional construct with more volume on the inside than on the outside?
It is better to be a warrior in a garden, than a gardener at war.
Some of us, on the other hand, actually prefer a religion that includes some type of correlation with reality.
