It doesn't make much sense, but if you really think about it, it MIGHT be true. But, personally, I think it it's a highly fabricated theory. There is no way that we, being as advanced as we are, could ever be created by supernatural creatures. We have done so many unique things and gone through so many scientific breakthroughs that it virtually eliminates the possibility of being a simulation. These events could not have been programmed or constructed, we as people have constructed them ourselves.

It isn't clear why complexity eliminates the possibility of being a simulation(?)
