This is rather simple, so I'll try to say it like I'm talking to a child, so you don't get confused. Don't wander off into one of a thousand conspiracies, Stick to what you claim to be true about 911 and post actual credible evidence to support your assertion that the hijackers were found alive and the planes were still being used. We all saw the planes crash and know that nobody survived. Your claim is lunacy.
This behavior is not very Christian like if you want to learn you might change your perception to encourage your teacher not act like an adolescent who can't get his own way. I have not attacked your mental abilities nor your maturity so please leave this attitude at the door.
The planes left an airport full of passengers. Many of the passengers used phones to contact loved ones before they died.
This can be easily reproduced by the tech we have today. Wire tapping has been going on for many decades making available these voice recordings to be made to sound just as if they were real.
The planes had transponders that were shut off. They had been on civilian radar and were being tracked. The plane that hit the Pentagon left behind parts of the plane and remains of the passengers and their luggage. These are what you would call evidence that proves something to be true.
Again these things can be staged they have been investigating plane wreckage for years. The startling facts are NORAD had been training for an air attack for over a year and yet they sent no planes up? I have heard they were given a stand down.
You failed to produce any such evidence. You simply wrote down that "they" had found 9 suspect still alive. You didn't say who they was. Was "they" your cousin Wilbur? Was "they" a kook posting on youtube from his living room? Were "they" merely saying "they" found Arabs or Muslims with similar names and tried to find simple-minded people who would accept that as being the same as finding the actual people who hijacked the flights? Who knows with you guys. You make up something every day and move on to a different conspiracy without ever providing any evidence to any our you made up conspiracies.
There is plenty of evidence if I can find it.... you with superiority intelligence? should surly be able to do your own search.
