conspiracy theory?
I guess most would be from the previous movie. You know the nonsense that we're too stupid to actually develop electronics on our own (we are just a bunch of monkeys after all), so we had to steal the technology by studying Megatron. Oh, and that cliche secret agency so secret that if you knew about it, they'd have to kill you. Oh, and from The Fallen, you have that alien device in Egypt with a pyramid convienantly built around it.
