Snakes did not evolve from lizards. Whoever said that cut a LOT of corners explaining what little is known about snake evolution. One of the earlier known snake like creature species from the late cretaceous period (145-165 million years ago)was Pachyrhachis Problematicus. A google search should find you some good artist renditions and fossil photos. These animals were believed to be closely related to what are now boids (boas and pythons) The rear limbs were never "legs". They were flippers for swimming. They didn't ever have any front limbs as far as anyone knows. It's also now believed that they may have grew these "flippers" and lost them perhaps several times through their evolution. Fossil evidence from snakes is rare. Their cartilage skeletons didn't leave behind many clues and left their past very dimmly lit compared to other animals. Even bugs and plants left us much more to go on. It's not likely that all snakes evolved from a common ancestor. Boids probably evolved from problematicus. Other types of snakes likely evolved from similar but different species.
I have never fully understood the argument between evolution and creation. It can be both you know? Perhaps God programmed in a way for them to adapt to the earth as the earth changed. I don't see where either argument discounts the other at all.
