@Dutch-Scientist : well i already told you i am not a JW, and that crap talk of an earthly paradise is in no means biblical, the bible clearly states the destruction of this earth, so I feel really bad for all the Jw's out there who think they are really going to be living on a paradise earth eating and driking and wearing nice clothes, they are practically delluded.
@Nicholas :
Genesis 6:15 in the Bible tells us the Ark's dimensions were at least 135 meters long (300 cubits), 22.5 meters wide (50 cubits), and 13.5 meters high (30 cubits). That's 450 feet long, 75 feet wide, and 45 feet high! It could have been larger, because several larger-sized cubits were used. But the 45-centimeter (18-inch) cubit is long enough to show the enormous size of the Ark.
(A cubit was the length of a man's arm from fingertips to elbow.)
Noah's Ark was three stories high (Genesis 6:16). Its total deck area was equivalent to the area of about 20 standard college basketball courts or 36 lawn tennis courts. The world had to wait until AD 1884 before the Ark's size was exceeded, when the Italian liner Eturia was built.
The rectangular dimensions of the Ark show an advanced design in ship-building. Its length of six times its width and 10 times its height would have made it amazingly stable on the ocean. Remember it was made more for floating than sailing, because it wasn't headed anywhere. The Ark was made to withstand a turbulent ocean voyage, not to be at a certain place at a certain time.
perhaps something like this :
again, let me point out that the ark wasnt made for travel, it was meant to just float on the water, and since it was the rain which lifted the ark i bet it was gradual,
and talking about the food issue , please know that this was meant to be done for just a period of time, its different from having to work at the zoo which is permanent.
perhaps you forget that all they did back then was farming(sherperds and famers) so they pretty much were knowledgeable about taking care of and feeding animals.
