1. No. You are assuming that the universe early on has the same properties as things in the universe now. We don't know this. Further there are quantum physicists who tell us that stuff pops in and out of existence all the time. And when we speak of the singularity at the start of our universe our Einsteinien and Newtonian physics stop working. We begin to deal with quantum physics and the realm of the unknown.
2. Why must there be a cause of the universe? Time as we know it began at the Big Bang so the idea of a before is non-sensical. And even if there is something else that caused the Big Bang, why must it be non physical? I've put forth other scenarios, why are they implausible?
