Yes, "impossible" miracles happened while building Noah's Ark that no
one has ever mentioned!
  First, the termites would have eaten it up faster than it could have
been built! The keel would have been just plain gone before the
planking was barely started!
   In a wood boat, They would have used tongue and grove construction
as well as wooden dowels to hold the frames or ribs together. Over a
few months, the wood would start drying out and these pieces would
loosen, then over a couple years start to come apart.
    You leave seams or gaps between the planks so you can push calking
fibers wool or cotton coated with pitch to make them watertight.
   However, As the wood dries out being out of the water, the gaps get
bigger and the calking falls out.  The pitch you coated the wood with
dries and falls off!
   So, you see, in all this God miraculously kept the wood from drying
out, the caulking and pitch fresh and pliable and the bugs from eating
it for over 100 years!
Maranatha, Lewis B
