Many scoffers of the Flood state that it would have been IMPOSSIBLE for an eight person Ark crew to have cared for all the animals. In reality, most of the animals would have required very little, if any, care once loaded onto the ship. The ark undoubtedly made use of self-cleaning, self-feeding and self-watering technologies. The above picture shows a 1/12th scale model of the type of feeding system that could be placed within Noah's Ark. Note the following regarding the system above:
It uses a mesh type cage floor and slanted waste system, which moves animal wastes into a gutter. Once in the gutter the manure could have been allowed to either dry (becoming odorless and inert), or made into compost by earthworms and bacteria, or it could have been dumped overboard by means of a slanted trough leading to the exterior. None of the waste would require human handling.
Food could have been loaded into the chute on the side of the cages and the animals could feed themselves. Enough food could have been loaded into the chute to last the duration of the flood until dry land again appeared on the earth.
Water could be piped to self-filling bowl or troughs. The water could be gathered through a rainwater cistern system or could have been pre-loaded before the flood. People of Noah's time commonly made indoor pipes from reeds, clay, and bamboo tubing.
An eight person crew on the Ark could have fairly easily cared for the less than 40,000 animals it held. Data from animal husbandry studies have shown that they would even have had time to keep the Bible Sabbath.
