Due to your unique location at the exact centre of your world, everything that you don't directly experience cannot be fully understood, as you cannot fully experience it from the exact centre of that world the experience comes from.
Because of this, there is a natural prejudice present for all things outside your personal existence at the very centre of your world.
This natural prejudice is often combined with human fear and can form belief in things you cannot truly understand, due to it being outside the exact centre of your world.
