Was 9/11 an inside job? Don't answer this unless you can give me proof.?

I do not think it was at all. But I hear about so many people, more and MORE people claiming that there is proof to it being an inside job. Firemen that were THERE as the planes hit and THERE as the buildings collapsed say nothing about any explosions. All I know that is proven is that planes were hijacked and flown into the buildings, tower 7 coming down due to the debris from the other buildings. Tell me.. no SHOW ME somewhere on the internet where there is some kind of interview or testimony from someone that was THERE talking about explosions or proof that OUR government was involved in the planning of this tragedy.
