Size of the Earth
...has obviously expanded greatly since Noah's day, when he could, in a short period, collect pairs of all animals and birds from all over the world, without the benefit of modern air transport. Then after the Flood, the critters all had to migrate, at the double-quick, to their present habitats in Tasmania, the Galapagos, the coasts of Antarctica, Patagonia, the American Southwest, or wherever. It's clear the Earth was no more than a few hundred miles across, probably flat, and with no inconvenient oceans like, say, the Pacific.
Has the author of this site even studied what Genesis says about these things? God brought the animals to Noah. (Noah did not have to travel all over the world collecting animals.)
