So I'm just banging my head into the wall here aren't I.
I hate arguments like yours, because you can say it to anything. I.e.- we think pigs can't fly, because that is what we know right now. Maybe one day we will find out that pigs can fly by altering their own gravitational field using some part of their butt we don't know exists or don't know the function of.
But here's what I will ask you. What is your belief that snakes can feel based on? If you are willing to accept that right now, the scientific community has found convincing evidence that snakes can't feel, then what evidence do you have to support your own conclusion? Just your own observations?
