To state it another way, why does the universe exist at all? Why is it not just a jumbled mess of superposition quantum states? We know at the deepest levels there is a wave-particle paradox to most of what exist, so what causes the collapse to happen so that particles can exist?
The standard answer is that the question itself is a form of survivorship-bias, meaning because our universe is one in which superposition states collapsed into regular particles, is what allowed humans to evolve to even pose the question.
However, there is an alternative, which is that the universe exist because the 'force of consciousness' was present to cause those collapses, which then in turn provided an environment which animals could evolve and eventually detect / interact with that underlying force.
It all becomes philosophy and metaphysics after a certain threshold.
