Recently FAIR was asked the following question:
How did 22 friends along with their wives and children board 8 barges and collected and packed in them “flocks and herds, male and female of every kind” along with enough food and water to feed them all for an ocean journey that would last for 344 days at sea?
Volunteer FAIR apologist David Stewart responded with this excellent reply:
As is often the case, the terse account in ancient texts with few details leaves many questions unanswered. The text says nothing about the Jaredites taking cows with them, and what the flocks and herds consisted of is pure speculation (we have some mention much later in Ether, but no discussion as to which of these animals were brought on barges and which were indigenous). At three families per large barge, there was clearly a large amount of storage space. The text provides no other specific details which would answer logistical questions. A variety of potential solutions could be posited in view of the scriptural parameters, but there would seem to be little point in engaging in such speculation. There are also some Latter-day Saints who view this story as literal and others who see it figuratively, just as many non-LDS Christians view some of the early content of Genesis.
The Jaredite story is clearly less fantastic than the Noah’s Ark story, or a great many other stories that have come down in ancient records, and the limitations of our knowledge must be kept in mind. Your question is therefore one which has little specific to do with Latter-day Saints, but engages long-standing themes of the Judeo-Christian scripture about which controversies are unlikely to be resolved anytime soon. One might as well protest in front of various Christian churches with signs reading “Noah’s Ark is a Lie” as to attempt to make hay of this much less problematic account in LDS scripture.
