To an extent it does seem possible. For example if you see the animals and plants around us, they are all basically robotic in nature. Eat, sleep, mate, reproduce, die. All animals including we are basically doing these things only. Isn't it something like being programmed. The bees collect honey from the flowers all their life. Who fed these instructions into their minds. Maybe those aliens who created us, maybe god, maybe just evolution. And as for the possibility of gaining freedom from these alien masters, I think in our own sense we are already free. I don't think they interrupt our actions.
