How do you demo a building while its on fire? Im no conspiracy person, but watch how that thing falls. It intentionally implodes on itself like a controlled demo. You cant just point a demolition gun at the building and make it fall perfectly like that. These buildings are not constructed with backup demolition systems in them.
The "implosion" is explained by the fire modeling and by other cases of steel buildings collapsing. Such fires are an uncommon event but in the last few decades there were several examples.
The fire burns uncontrollably through the interior, with the fire suppression system out of water due to the main being cut off from prior events. In a few hours the fire resistant materials expire and the temperature of the beams and columns reaches a point where they start to distort - as they distort the bolts start failing from the unbalanced loads, and entire sections drop.
The interior collapses first, as seen from the fuil WTC-7 video, and after the interior collapses (with the roof structure visible falling through), a few seconds later the outer envelope, now unsupported, starts sheering off and collapsing upon itself.
Its amazing how perfectly WTC7 fell directly into its own footprint.
Because it was demoed as a fire stop.

Myles Power made a video about WTC7: https://youtu.be/7PpsCCTMP8w
I don't endorse him on other topics, but this particular video is good.
