Of Snakes, Amphibians, Men, and Brachiosaurs

Brachiosaurs, a kind of dinosaur, is essentially a snake with legs, giving credence to the Bible theory that snakes once walked.  In that sense, they are similar to amphibians, such as salamanders that evolved to no longer have legs, becoming snakes.  Remember, the snake was told it would have to crawl on its belly as a punishment.  Meanwhile man was to suffer from back pain, and it is also true that many people suffer from back pain.  What I am suggesting is that snakes evolved to no longer have legs.  Granted, I completely understand the similarity between us and dinosaurs in that we have a one way digestive tract.  However, one of us came to walk and the the other came to slither on its belly.  Additionally, old world snakes, such as pythons have the boney remnants of limbs within their body though you wouldn't know it by just looking. It is only upon dissecting an old world snake that the remnants of its limbs may be found.
