You're not wrong that 9/11 is a "controversial" topic and there is a lot of speculation on it, I just wanted to throw a few things into the mix.
First off, I have no doubt in my mind that the "official" version of events is complete fabricated junk, and even that label is giving it too much credit. actually, let me put the discrepancies I know into a list, this is by no means all of them but some of the most glaring flaws of the official narrative.
A building hit on one side does not collapse into it's own footprint, it should have bent and fallen sideways like the top of a tree when it's been hacked at with an axe
the top of the building would not crush everything underneath it at free fall speed, the rubble would be impeded and should have taken around ten times longer to crush what was under it
Footage of the tower fall shows massive jets of dust and debris shooting out from just a few windows at least 10 stories under the collapse point
Aircraft grade kerosene (QAV) burns in a controlled environment (kind of like gasoline burning in the combustion chambers of your car) at around 2200 degrees Celsius, but in open air, only around 1000...as I learned in high school, an oxy-acetylene torch burns at over 3000 degrees Celsius and even that takes time to melt steel, the impact of the shell of the plane would have done far more damage than the jet fuel would have (most burnt off in the air after impact, interesting fact, I tried a butane torch on a thin angled piece of aluminum that was set to burn at around 1200 degrees Celsius, and it didn't even want to bend.)
They expect us to believe that an aircraft black box was destroyed in a crash (the initial story) but somehow they knew the high jackers because they found their passports among the debris? Last I checked paper and cardboard could withstand very little punishment (Although an Insider article from December of 2018 says the black boxes were "never recovered"...funny how the story changes when convenient.)
A phone call was made at 32,000 feet when the chances of that call actually connecting at working was a small fraction of a percent (And for some reason the guy calling his mum used his first name and surname...when have you ever needed to use your surname to identify yourself to your own parents?
)
Building 7, one of Silverstein's buildings was also demolished despite having suffered no fire damage at all. (in an interview, Silverstein said he authorized demolition at advice of the fire department, despite the fact that a building demolition is something that takes days to plan, it's not like throwing up a shed in an afternoon.)
The part of the Pentagon that was hit was not only not burned in a fireball but the wing span of the jet was WAYYY wider than the actual site of impact.
That's to say nothing of the other claims I've heard but can't confirm or don't have pics to back up:
The base struts of the tower look like they'd been cut with an angle grinder, some accounts say thermite was used
There was a fire in the base of the towers that firefighters were simply unable to put out (again, points to thermite, a simple but very powerful high heat compound)
The wing of the Pentagon that was hit held financial records for the US government that proved there was a few trillion dollars unaccounted for in the US budget
There was supposedly evidence of a case about to be served on Bill Clinton in one of the offices of the twin towers,
At the end of the day though, this was a public power play by someone who was looking to push forward in a plan bring the one world government closer to a reality (No, not George Bush Jr, he's way too fried on whisky and cocaine to be intelligent enough to pull of anything close to something like that, he was like the warm up for Creepy Joe Biden.), and it was probably made so public to cover up something else, but there are so many levels to things like this that we will probably never know the actual truth about the how and why in this world.
At the end of the day, the bible tells us the base reason why this happened, Satan hates humanity and wants to bring his world system to earth, but will be cast into the bottomless pit so there is no hope for him...there is however hope for those who are still alive to come to repentance and faith in Christ for the forgiveness of sin. The prophecy of Revelation was written nearly 2000 years ago, and there are parts that we are seeing fulfilled today, but Jesus did say it's not for us to know the times and the seasons for these things to come to pass, so all we can do is work to deliver the gospel.
In short, yes, the official story of 9/11 is as rotten as the morning after a taco-bell binge.
