Proof is in the footage. You just see it differently.
The relocation of the oem command center for the 9/12 simulated terrorist attack operation.
The original location of the oem center on the 23rd floor of #7, and the just in time completion of the 13 million dollar addition to #7 prior to 9/11.
The acquisition of the entire WTC by Manhattan developer Larry Silverstein just six weeks before 9/11.
First time the WTC had changed hands in thirty years and the first time it had ever come under private control.
Only 56 minutes to fall.
Timeline.
Insurance.
They knew it was coming, and gave it a helping hand.
They've been at it ever since.
the beams that were used in the towers would've been very VERY thick and held together with other beams

I've seen something like this before.
While steel does melt at a much higher temp that what burning jet fuel can produce, the steel does not have to be melted to become structurally-compromised.
Good video.
So what about all the steel that was not compromised by heat.
#2 fell in 56 minutes! #1 fell in 85 minutes!
1975 WTC #1 fire burned for 3 hours on the 11th floor while spreading to many floors. This fire was more intense (hotter), and suffered no serious structural damage from this fire. In particular, no trusses needed to be replaced.
I think another member mentioned that the structure was not held together through welded joints. It was bolted together. Given enough force from the impact, the fires and the collapse, those bolts were nothing more than sheer pins that broke easily.
In other words, the pancake effect.
So the tower's construction and massive weight was trusted by bolts since day one?
Why didn't Tower #1 collapse in the 1975 fire that burned for 3 hours at a way lower level (many floors around floor 11), which had a lot more weight above than 9/11.

Office furniture would not have done anything to the structure.

The proof for that is the requirement for steel being insulated in building codes.
missing 3 trillion,

Almost all the kerosene fuel was consumed in the initial fireball outside the building.

The core (47) columns were mostly welded, but only to maybe 1/2 depth and only on 2 sides. But the top ..... 15-20 were bolted.
The exterior columns were mostly bolted except for the bottom few floors.

4- as others have noted, lower floors have heavier thicker steel. Heavier thicker steel heats slower the the plane impact floors
