I believe in what I can feel in any way.
And yes, I think, there should be some cause of Universe's birth. But what cause? Is it some sentient being?
Or it's just usual "law of birth of universes", like Newton's law in mechanics?
By the way, there are some elementary particles which appear from nowhere and disappear suddenly. We can't view such particles directly.
What if our Universe is such particle in huge "Superuniverse"? This particle (called "Universe") just appeared suddenly, following some unknown physical rule.
But anyway in this case the question remains -- "Who created Superuniverse and this unknown physical rule?". It's like problem of chicken and egg.
About dimensions -- no much interesting about. In Kotovaya I've already wrote about string theory with 9-dimensional strings and branas.
In short: physicists assume there are other dimensions. Each point of 3D space can be described as sphere, inside which other dimension are "curled".
But these dimensions are too tiny to be seen.
BTW one of task of Big Hadronic Collider is to find indirect evidence of other dimensions.
