911 conspiracy

I never really belived in conspiracys, but ive been watching some videos lately of the theory that the united states government planned the attacks on the world trade center and pentagon to have a reason to fight a war on terror without the united states citizens goings absolutely insane. I dont want to believe that this is true but some of theevidence is pretty convincing. First is how perfectly the towers fell down almost as if they were on timed explosives. Second is that tower 7 which is 47 story building across the street actually crumbled to the ground also and was NEVER HIT with anything at all. That is the one that really scares me the most because no terrorist would have access to so manyexplosives and would notbe able to plant them inside abuilding so easily. So why did tower 7 really fall?
