Do you realize that only 3 steel buildings in history have fallen due to fires. They are the North Tower of the World Trade Center, the South Tower of the World Trade Center, and World Trade Center 7.
Do you really believe jet fuel can bring down a building perfectly symmetrically.
The World Trade Centers were designed so that multiple 707 jets would hit them. Thats why the designers were stunned when the building fell.
Prof. Steven Jones of BYU wrote a paper about how the World Trade Centers had to have been brought down with the use explosives, so it was a controlled demolition.

Oh, and I consider myself to be a coincidence theorist, not a conspiracy theorist.
