Answer: Scientists have made studies of the animals that the Bible says were on board, and the average size of the creatures was perhaps a bit bigger than a rat! Only about 11% of all of the animals on the ark would have been much bigger than a sheep. Also, Noah could have taken many young animals, thus saving even more space.
Reason #3: Noah couldn't have taken all of the fish, and even the whales!
Answer: That's right, he didn't, but not because there wasn't room. Fish are not land-based and don't breathe air through nostrils. Whales do breathe air that way, but are not land-based. These types of creatures, therefore, could have survived outside the ark in sufficient numbers to keep their kinds alive until after the flood.
Reason # 4: The Ark would not have been a very steady boat.
Answer: Yes, it would have been very steady. Tests done on models have shown that not only was it steady, but it would have been almost impossible to capsize.
Reason #5: Noah was not a shipbuilder, so he couldn't have built the ark.
Answer: Yes, he could have, and here are some reasons why: First, Noah had up to 120 years to build the ark (see Gen. 6:3). Also, he probably had help (he might have even hired people), so this task certainly could be accomplished. Also, Noah was not building a boat or a ship. Those vessels need a prow and an energy source to go somewhere. That's not what the ark was. It was an "emergency floatation device". Furthermore, the word
for "ark" in Hebrew means "box" or "coffin" in English. Noah was not building some complex machine - he was building a giant box that was then covered with pitch to seal any leaks.
The global flood was God's idea, and He certainly saw to it that the ark was built right, the right size, and that it could withstand the pressures exerted on it during the judgement.
