Noah's Ark: could have carried that many animals?
According to the Bible, Noah's Ark was a massive vessel built at God's command to save Noah, his family, and a core stock of the world's animals from the Great Flood. The story is contained in the Hebrew Bible's book of Genesis, chapters 6 to 9.
The Ark had a gross volume of about 1.5 million cubic feet (40,000 m³), a displacement a little less than half that of the Titanic at about 22,000 tons, and total floor space of around 100,000 square feet (9,300 m²). The question of whether it could have carried two (or more) specimens of the various species (including those now extinct), plus food and fresh water, is a matter of much debate, even bitter dispute, between literalists and their opponents.
According to one school of modern textual criticism—the documentary hypothesis—the Ark story told in Genesis is based on two originally quasi-independent sources, and did not reach its present form until the 5th century BC. The Ark story told in Genesis has parallels in the Sumerian myth of Ziusudra, which tells how an ancient king was warned by his personal god to build a vessel in which to escape a flood sent by the higher council of gods. Less exact parallels are found in other cultures from around the world.
