Back to uni, starting my bachelor in philosophy for real

I'm writing this one in a hurry too. I just got back to uni, studying for my bachelor in philosophy at UiA and UiO and I came across something interesting. A new point of view so to speak. You probably know by now that I don't believe in God, in heaven or hell or in anything like that. That could lead to a situation where our actions or life itself doesn't matter as much. I have someone in my life that I love and I feel that I should at least try my best in life to help contribute in making the world better for humans in general, or at the very least- avoid being a liability to society. However, beyond these trivalities I have now found another optimistic(?) reason to be good.

You see, out of the many absurd arguments or theories within epistemology there was one that I actually found to be, not just difficult to argue with- but a likely one. At least, it seems a lot more likely to me than the theories within religion. (Which does offer some good incentives in terms of ethics).

The possibility that this is all a simulation, that I am a brain in a vat or that I am really somewhere else in the universe living this life as while playing a highly sophisticated "game", running through a test or something similar. Perhaps in order to learn something about humans or some other species, perhaps as a test to see whether I qualify for something else, there could be so many reasons why. I am not alone in believing something like this to be likely. One reason for this is the fact that we have been unable to find life outside our own solar system. Maybe we have just been unlucky so far, our lifespan has been short compared to the lifespan of the universe, but when considering life it is not unreasonable or hard to imagine life and other species that have developed to stages much further away than how far we have come both through evolution and through science and technology. To species and a world where a simulation as detailed as lives like ours might be a simple feat? There's also another argument about how the planck length tells us something that could support this theory, but after closer examination, maybe it didn't. Looks like I don't have a lot of arguments to support it at all, but my point was never to convince you of anything anyway. I just thought it was an interesting theory that I don't find as hard to believe as for example religion and if this really was a test or something, then I don't want to fail it.

This type of motivation would mean I'm mostly being good to possibly save my own skin in another/ real world, but it is vaguely interesting to realize that I seem to be sure of even less than I'd already concluded with. I didn't think that epistemology would thwart me further, but this one was pretty good. Matrix comes to mind and you can laugh if you want to, but as the sceptic would say: it could be true! Sceptic arguments often still annoy me though I'm much more patient now when I endure their arguments, but this debate is open for a reason and since it's a part of my education I need to engage in it like I am doing now through writing, or through discussing with other students or friends.
