Is world a videogame?

Is it possible that we humans are a creation of another, more evolved and superior race, just the way we create characters in a videogame? Everyone must have seen the children playing with toys making them talk and interact while themselves doing all the talking and thinking on behalf of toys! As if the toys were live and intelligent for each other. Suppose this was really the case, then? In a videogame of say, a cop chasing a thief, the cop and thief in the game do really exist for each other but act as we programme and direct them. Once the game is over, they simply cease to exist. Now suppose they start evolving and become intelligent due to our programming, then they may start acting according to their will and not exactly as programmed, may build their own new things, which are real in their world but illusory for us. If some enlightened ones among them tell others that their world is but an illusion, and try to discover and reach us, their creators, then could it not be akin to the human race trying to discover God? The idea may seem to be a figment of imagination too far fetched but then it is still less bizarre than the one of cloning or making robots or going to Moon and Mars was, a century ago.
