EVER existed? Seriously, using the same standards of "proof" and the creation of various new and amazing technologies....or perhaps some form of mass hypnosis (Anybody see "The Shadow" with Alec Baldwin and John Lone)...... why could one not postulate that the Twin Towers.....never existed at all?

The no-planers have it slightly wrong. The planes were real, the WTC towers were holograms. A lie is easier to tell the more absurd it is. Hitler knew this, so did Bush.
