To be perfectly honest, I always thought that if there were to be such things as gods (I'm agnostic), it would probably be a computer program/simulation. To me, it's always been surprising to me how we humans have kept the faith in well, faith, even at this stage of technology and understanding of the world around us, when the ideas of mystical beings were created my ancient humans who couldn't explain phenomena like day and night cycle, eclipses and such. So the concept that we are just lines of codes in a simulation is just as possible as other religions. Just as the theoretical god s could have <insert any religion's back story/explanation>, theoretical programmers (who might also be higher, more intelligent beings or even "gods" to us) could have programmed us lines of code to be self-aware yet have an algorithm that never allows us to find the truth of the programmers, or they might also have implanted the ideas of mythical gods to distract us from finding the truth, or maybe they're merely doing this for amusement, to see whose simulation becomes aware of the programmer first. It might be a self sustained program or a a controlled simulation. Therefore if it is true that we are just a part of a computer simulation, there would theoretically be nothing we could do about it. The programmer might get amusement that his universe became aware of him, and then shut out universe down with a cosmic disaster or simply reverse time or unplug the simulation. Since we would just be lines of code at that point, the programmer could easily eradicate/control our every move in the simulation. Another possibility however is that the programmer is dead/abandoned the self-sustaining simulation, and at one point we figure out how to transform our lines of code into the physics of the programmer's world. One perspective I look at it is that we are to the Programmer as the people in Sims are to us - except that we are self-aware and the Sims are not. Or maybe that's just what we think...or what our Programmer wants us to think... However in conclusion, if all this is true or not, I doubt we will ever know in our lifetime.
