Do you believe their estimation of the length of a cubit to be innacurate ?
I'm not sure. I have no way of knowing how the people at that time and in that place measured a cubit. Others with a better understanding can look at this claim. I was merely pointing out that basing an argument on an assumption that yields a "perfect" result is less than convincing.
Also, they based their shape of the ark on people who claim to have seen the ark on Mt. Ararat. Considering I'm convinced the ark is not on Ararat, this again fails to convince me.
Also, they acknowledge that their techniques assumed for shipbuilding were based on modern techniques and technology, while saying they assume the actual builders did not have access to these techniques or technologies. They assume that maybe trees grew differently in the past than they do now.
They also have no actual practical experiemnts, all of it is done using math, which we have shown don't work in actual practice because a wooden ship of that size seems to work out on paper, but when put into sea, it leaks because of factors not included in the math.
All in all, this whole page starts with assumptions built on assumptions leading to math of dubious accuracy in real world applpications to create an answer they were sure of from the start.
