You asked, man.
It seems odd that the collapse of an adjacent structure would result in such widespread interior fires. That being said, I can't say what started the fires. By what method would upper-floor fires reach the sub-levels of a building like that, unless that building burned to the ground? What risk could sub-levels of such a building have of being set ablaze by falling debris? It's the obvious location, both for maximum structural impact and maximum 'safety'/discretion, for any potential 'explosives' scenario in the building 7 collapse. I'm not here to cook up scenarios, though.
Building 7 was a repository of records and place of business for several major insurance brokers, several major banking institutions, the IRS Regional Council, the U.S Secret Service, the CIA, and contained the NYC field office of the FBI. Much of the data they housed was financial in nature. I'd say it's entirely possible that the atrocity of the attack on the twin towers, as well as meant to inflict upon the nation a state of almost universal and exploitable trauma, also served as a cover for the destruction of Building 7, and all the data within.
Being more or less next to one of the world's tallest structures as it violently and rapidly collapses somewhat precludes the possibility of there not being a debris hit.
Right. You've been shown physical evidence of explosive residues found in WTC dust. You've been shown a physical demonstration of how home-made, non-controlled thermate can be used, in relatively modest quantities, to cut steel, even vertical beams, with relative rapidity and a bit of engineering know-how... proving the bold claims that such a scenario is physically impossible entirely and flat-out false. You have the footage of WTC7, which appears to collapse in a way distinctly similar to that of a demolition. You've got many multiple testimonies of explosions being heard/seen/felt. Please, apply some fact-based rationality and explain to me why NIST tested neither dust nor steel for even the possibility of explosive residue, and why that decision was appropriate.
