What if i told you 9/11 was a CIA inside job?
I would say it does not make sense.
But people who want to believe convoluted conspiracy theories can always find an excuse for every difficulty with the theory.
It is very difficult to disprove a conspiracy theory.
You have to resort to Occam's razor, and if you do not have common assumptions about the nature of reality, that does not work.
There are people who claim it was the CIA, the Mossad, the U.S. government generically, the person who owned the building, etc, etc.
Those that claim the CIA always have a convoluted reason why the CIA would want to do it.
It is all complicated by the fact there have been and are actual conspiracies, such as the conspiracy to frame President Trump.
I find the most interesting are the Arab Muslims who are masters of claiming a conspiracy of the Jews for everything.
One moment they will tell you it was the Jews that did it; the next they claim it was the greatest Islamic raid in the last 100 years, a great prideful boast of Islam.
They believe both realities at the same time. They don't seem to have any problem with believing two or more contradictory things at the same time.
There are many people who believe every war is pre-planned, with the results known years in advance. Those people have completely different assumptions about the nature of reality than I do.
