Alternatively, the fact that we don't yet know how the universe came to be doesn't imply that there has to be some great power that created it.
Things are happening all the time, of course, but there is no need to see meaning anywhere. Humans have a strong need to seek meaning, and will even go so far as to make it up where it does not exist.
If everything that exists has a cause, and a higher power that created the universe exists, something else must have caused it to exist. What caused God?
This is one of the ontological arguments for the existence of God. Any intelligible first cause must have a prior cause. Therefore the first cause is unintelligible. The thing which caused the universe is beyond our understanding.
