Incomplete Past Directions of the Universe in Cosmology; Theo-philosophical Implications & Consequences

We can introduce two classes of scenarios. The first, standard model of cosmology proposes a scenario in which the BigBang is beginning, and the second, scenarios where the BigBang is merely a gate to our universe and the universe have more dimensions than ours. The basic question is why and how did the universe come to be out of nothing? To answer such a question, two methods have been taken in the physics: firstly, finite but no boundary model and secondly, the scenario of eternal inflation. Having explained the two classes, I will show that the main experimental and theoretical evidence support the past incomplete directions of the universe; whether we consider it as Big Bang or more developed. Also, the existing models and scenarios are not against the supernatural approach, but also consolidate it.
