If its all just a sim, I would have to imagine its either some type of entertainment (tv show, video game, gambling) or necessary training to enter the next level of simulation or real life (could be extremely hostile in many ways) or just a way to keep your brain active in the real world (Matrix slave style, or your dead and your brain is in a jar and the sim is just here to keep your brain firing until you can be put into a new body, human or machine)
If its all just a sim, the odds of us being able to prove that, is about as likely as our GTA sims realizing their sims, and proving it.
On a lighter note, if I HAD to ask them something, I'd ask them who the heck thought it was a good idea to make me like gaming, but also give me strong country roots, where the internet is intolerably slow, and whether or not that life form has been fired yet!
