We had about a million videos of the attack on the WTC and they show two planes hitting the Towers. When the structures collapsed it showed the collapse from the top down. There isn't a single case in the history of intentional explosive demolition where the floors collapse from the top down. Google up typical explosive demolition and you will see obvious detonations usually starting on the bottom.
I'm guessing you missed all the reports of lower floor and basement explosions that happened PRIOR to the collapse.
Conspiracies always have a reasonable theory regarding the intent such as FDR wanting to get the US into WW2 by encouraging the Japanese to attack Pearl Harbor but the tinfoil hats offer no political or any other reason for the 9-11 attack.
There were PLENTY of reasons offered, you must've missed those, too, even though they were enumerated in the OP.
A conspiracy would have to include the entire democrat party including president Clinton and extend into 7 months of the new Bush administration. Are the tinfoil hats willing to implicate Clinton?
No it wouldn't. It would only have to involve those at the very top. It's not hard to imagine them having identical goals when they're all members of the same secret societies. When they ALL get their marching orders from the same puppeteers.
How could a mysterious rogue unit coordinate split second timing with crazy jihadists and where was the FBI and the CIA and why the hell would Americans intentionally destroy the symbol of Capitalism in New York City as well as the Pentagon and God knows where the 4th flight was headed? Nothing in the realm of conspiracy makes the slightest sense. What are the tin foil hats thinking?
Split second timing? WTF are you talking about? All they needed was for the jihadists to hit the buildings with planes, it didn't matter what day or time.
You ask where was the FBI, I encourage you to Google 'Able Danger'.
You ask why the towers, I encourage you to Google 'Asbestos removal & mitigation'...
You ask why the Pentagon, Google 'Rumsfeld missing trillions'...
Get back to me when you finish your homework.
