I haven't yet managed to fit inside a toothpaste tube. But you believe in the impossibility of this right? There is no absolute belief or disbelief. It is all a continuous gradation. Some things we can bring ourselves to belief in if there is sufficient cause. Not arguing for or against the original point but just your argument and condescension.

I believe I cannot not fit into a toothpaste tube for entirely different reasons than "nobody has ever done it." The latter is the assertion here.
