I am a relegious person also. Christian to be exact, I have a 3 year degree in theology and I can tell you that snakes are not a symbol of satan.
The "being" that tempted eve in the garden had leggs. This is evedant in the fact that God condemed him to Crawl on his belly "Like a Snake". in the beginning he had leggs and therefore was not a snake and after it was condemmed to crawl on his belly it was LIKE a snake and therefore no a snake.
