Like, "How did it happen or even could it have happened?" and, "How exactly is that information 'evidence'?" and, "What credible sources do you have?" and, "What is your argument?"
We know how it happened. The buildings fell down because of explosives. If you ask why. Because science tells us steel metal grids don't give way like a pack of cards because of a fire.

The information is evidence because it reveals that the building doesn't fall down by itself. The sources are credible because they involve truthful and objective observations that can be verified and backed up by history. My argument is that the buildings didn't fall down without the use of explosives.
