We try to put our human understanding on the line and say that since we need to have this or that and a snake does not have either, therefore they can't have feelings. Well who's to say? Why can't we realize that just because we don't know something, doesn't make it imposible. Humans discover new things all the time. When did the first boat float on water? When did the first plane fly? When did we realize the Earth was not at the center of the universe? Before all of these discoveries, we knew we had the answers, then something changed. A discovery was made and now we know how to build a boat, build a plane, realize we are just a small blip in the cosmic scheme of things. We make discoveries all the time, then our perceived world changes. Not before the dicovery, but after.
You completely missed my point. You say that Pigs don't have the wing structure necessary to fly. Snakes don't have the BRAIN structure necessary to feel. We used to think the earth was flat, and we know now that it is not. We used to not understand the structure of the brain, and now we know a whole lot about it. One of the things we know is that there is a part of the brain devoted to emotion, and snakes don't have it.

So you see, we have discovered that snakes can't feel, just the same as we discovered the world was not flat. Through scientific investigation. The proof is there, the physical, scientific proof is there.
