I believe God did create a better world, could not our sin cause
imperfections? Like worry, murder, cancer, TB, Aids, etc.....
If you believe in the Bible, which I do, people tended to live a lot
longer in ancient times.

Great post Mike, on thing that comes to my uneducated mind is that If a
neck was so long why would the blood pressure that it took to get all the
way up to the head not explode the brain when the animal lowered it's
head? Your post remindes me of the guy (and I cannot remember who :) that
open up a package of parts disguarded the instructions (or the Bible) and
when finished had several nuts and bolts left over. Yes everything worked
but maybe not as it had been designed. I have not heard of anyone
re-routing nerves or veins. When all else fails I fall back on the old
saying if it aint broke don't fix it.
