Seriously this debate pops up its head time after time.

Someone will always point out Loose Change which is a ridiculous joke of a movie. Besides the obvious mistruths in it (There was no aircraft wreckage at the Pentagon, and we've seen a lot of pictures of wreckage) To some pretty clever use of questionable witnesses. To Alex Jones continually reissuing the movie as his "Theories" get disproved (I.E. Cellphones from planes)

I remember watching a special on the learning channel where the engineers for reopening the 9/11 investigation were laughed at by engineers who had actually tested their theories.

The only conspiracy that happened was the failure of the Clinton Government and the Bush administration to act on the intelligence that was given to them.

If you read the book the looming tower it does a pretty good job of proving Al-Qaeda's roll in 9/11. Also read Ghost Wars which goes from the formation of Al-Queda and their actions leading up to Sept 10.

Popular Mechanics does an excellent job of disproving the Conspiracy theories in terms of the actual mechanics of the destruction of the tower.

There are also multiple sites out there that disprove the use of Thermite and so call theoretical Super Thermite as a demolition agent for the Towers.
