"No one has ever disproven the atomic bomb, but that does not make them any less harmful. Nor does it minimize the damage they can do. Maybe someday someone will disprove the bomb and make the world a safer place to live."
Unless the last survivor of the planet Krypton were to crashland on Earth - in a capsule & as a child - raised by human parents, who becomes a mild-mannered reporter for a major metropolitan city newspaper which is the alter-ego of Kal-El, a.k.a. Superman, and who destroys all the nuclear weapons in the world himself, then I'm afraid that - via my analogy - use of Bad Analogy (yours), your argument is invalid.
...oh, and as for "Dont you think that if evolution could be disproven, it would be disproven by now?', you haven't answered the question!
But I can: http://en.wikipedia.org/wiki/Escherichia_coli_long-term_evolution_experiment
Therefore evolution proved. I'm afraid that once a gap has been filled, it cannot be uninvented, which is the word you were looking for, I suspect.

"So I guess you admit that evolution is just as real as the atomic bomb?"
I guess Theo here - as long as he never travels to Japan, nor watches any documentaries about the latter part of the War in the Pacific half of WWII - thinks that the survivors of Hiroshima & Nagasaki will never exist. So, Theo: Japan won the War in the Pacific, then...?! [/paradox]
