There is more scientific proof suggesting Building 7 was destroyed by controlled demolition than the resulting fires from the debris.
A new scientific study found the official story surrounding 9/11 was not compatible with the laws of physics. Several studies have already reached similar conclusions. However, this is the 1st to provide the long-awaited definitive answers.
The new study conducted at the University of Alaska Fairbanks took things one step further – we now know with a high degree of scientific accuracy that the official NIST explanation of how the World Trade Center 7 building collapsed is not only suspect, it’s 100% false, according to the findings of this academic study.
This study replicated and remodeled every factor relating to that infamous day involving building 7. Complete study results and the undeniable scientific evidence indicating Building 7 was a deliberate job on the next page:

The level of ignorance in your comment is astounding! It takes months for a professional company to come in and plant the proper explosives in the proper places to implode a building.

Don’t know who did it but obviously a demolition job
No one has to try and be an expert there’s hundreds of experts that attest to the fact
All of those buildings were destroyed by demolition! There is evidence all over that thermite was used to bring them down and there’s also evidence that they had the fuses to those detonators on one of the floors that was leased out. During the time that they supposedly were upgrading the elevators is the time when they had armed guards protecting those entrances for a period of months and that’s when they put all of this together. All of the demolition experts that have looked at this thoroughly know exactly the truth about that. you could not get molten steel from just mirror fire it’s not hot enough it took thermite which brings it another thousand degrees over temperature of what the fire had provided. not one building fire in the United States or anywhere else for that matter has caused a building to collapse on itself. it’s just not possible. The fire alone is not hot enough.
THE TRUTH COMETH OUT.
No engine was recovered from the Pentagon crash
No engine was recovered from the hole in the ground in Pennsylvania after the United flight went down. You fly a jet into ground/building at 600 miles an hour THERE IS nothing left but small pieces. Ever been to a crash site?
