what about the construction. we’re talking about a boat that’s 450ft long. that’s a huge undertaking that requires lots of men and material.
roman emperors were able to command such feats for their giant pleasure boats (which were almost always in lakes because the ocean would destroy them in minutes). that’s not counting the manpower needed to aquire all of the animals that are supposed to be on the ark as well.
there are some major hurdles that need to be worked out besides whether or not a boat of such dimensions would be sea worthy.
Don’t you think God would see to it that no storm would capsize it, provide material and manpower, you know, providing it WAS His plan and all?
You forget that it was a (relatively) short time after the Fall of Man in Eden during which the Ark was built. Noah lived to be 950 years old, remember (Genesis 9:29) - the men of this era were no doubt endowed with abilities far superior to the men of the modern era. (Perhaps the Nephilim (Genesis 6:4) were in Noah's paid employ?)
Men in today's era are exposed to much more radioactivity than from Noah's age. The water from the Flood came from both the vapor canopy in the upper atmosphere (which blocked harmful cosmic rays), and from the Fountains of the Deep (which, brought with them, the radioactive isotopes from under the earth that we find in the environment today). (Genesis 7:11)
Not only does this explain why men in and before the Flood era lived such long lives and had "superhuman" abilities (see the Pyramids, for example), it explains why radiometric dating is such a farce, since it doesn't calibrate properly for the effects of the Flood.
It took Noah and his sons 120 years to build it.
