EntirelyPossible,
When you can build something bigger than a toy boat, let me know how your math works out.
Done. The math works out so that the ark would be totally destroyed in an open sea.
That was easy. Next.
The ark was a floatation device not a luxury ocean liner.It's sole purpose was to provide salvation from God's wrath. You act like it was supposed to cruise all over the world.
The ark of salvation carried Noah's family high above the deep waters of a drowning wicked and doomed world judged to annihilation, a way of salvaging those who were righteous in God's eyes.
