Similar arguments are made in scientific discourse. If you assume that the universe happened by chance, and the observable universe is just a part of a bigger multiverse, then you can ask yourself what is more likely: 1. The whole, enormous universe happening out of nothing, including you 2. Your small brain (no offense, we compare with the universe :P) happening out of nothing in a mental state that contains all memories of a world existing as you experience it now Option 2. seems to be more likely, and at the same time most people would call it absurd. This tough experiment is called Boltzmann brain. https://en.wikipedia.org/wiki/Boltzmann_brain https://en.wikipedia.org/wiki/Boltzmann_brain So, do you think you are a Boltzmann brain? It seems like answer to this type of problem depends fully on your a prior's. It's a big problem in cosmology: https://en.wikipedia.org/wiki/Measure_problem_(cosmology) https://en.wikipedia.org/wiki/Measure_problem_(cosmology)
