Re: NFC: DP -- Turtles



I would much rather read about reptiles, amphibians and Darwin than
Creationist beliefs.

Let's not start this again.  There are theological lists available for those
afflicted with the need for God and discussions thereof.

>All of the info in the second and third paragraphs just suggests the master
plan of a creator-God.  Before you dismiss me as a kook of some sort, I ask
you this simple question:  where is the physical evidence to support the
theory in the first paragraph?  There is none.  I have had this discussion
with others before and the belief that such evidence exists and will be
found or did exist and was destroyed by carelessness of previous human
generations.  In my mind it is easier to believe in God then it is in the
above.  Afterall, it is more plausible that we were created than a result of
a series of genetic mutations (or mistakes).

this theory.  Not all of us on the list subsrice to it (including the person
posting it).  You can respond if you like, but let's leave reptiles,
amphibians and Darwin at home from now on.
