You think the eyes emit light. Your existence - never mind your argument - is invalid, Casshiterides.
"ok then, professor. based on that logic, how can you even assume that you exist? how can you prove it? if all your proof is based on your observations, but you cant be entirely sure that you exist, then all your evidence is garbage because you cant assume that you actually exist and you cant assume that you can actually observe things."
Considering those scenes in "Dark Star", with Doolittle & Bomb No. 20, without the benefit of a neurosurgeon & a TV camera, or at least MRI apparatus, can Casshiterides prove his brain exists? I mean... 'Cogito ergo sum' is right out for him, as one requires the capacity to think in a cogent, nay, intelligent way to determine whether or not he is.
...and if one were to ask him that, his head would explode like a Thermostellar Device. >:D
"see? i can take things to the extreme and make the seem foolish just like you."
Compared to Casshiterides, you're Bertrand Russell. He took the religionists' 'beliefs' to it's ultimate extreme, and came up with the notion of his 'Teapot'; can fundies disprove the existence of such credibly & logically, without calling into question the very basis of their own 'beliefs & 'faith'...?!
His Noodliness the Flying Spaghetti Monster, and all that jazz. RAmen.
That's how I work sometimes, re. my Argument Annihilation techniques, after all.
