So I have been trying to convince my friend about the existence of one God who created the universe and I brought up the Big Bang. My friend believes that the Big Bang was just an event that happened in an infinite universe that is above ours to create a universe 14 billion years ago. I tried to search up answers on how to deal with his claim as I have never encountered it before. How would I disprove this claim?
I am a physicist and I think that a rational analysis of our scientific knowledges provides strong and convincent arguments supporting the existence of a personal intelligent Creator.
In fact, all what science shows about the universe is that it manifests itself as a realization of some specific abstract mathematical models (what we call “the laws of physics”); in fact, the subatomic components of matters (quantum particles and fields) are actually only abtract mathematical concepts. Also all the hypothesis about mutiverses etc. are based on asbstract mathematical theories. On the other hand, mathematical models are only constructions of the rational thought and a mathematical model can exist only as a thought in a thinking mind conceiving it; this implies that matter (and the physical universe) is not the foundation of reality, but its existence depends on a more fundamental reality i.e. consciousness: contrary to the basic hypothesis of materialism, consciousness is a more fundamental reality than matter.
Therefore the existence of this mathematically structured universe implies the existence of a conscious and intelligent God, conceiving it as a mathematical model. In other words, the universe can be only the manifestation of a mathematical theory existing in the mind of a personal God.
Personally I think that atheism does not account for the existence of our mathematically structured universe and denies, without any rational arguments, the only rational explanation.
There is another argument from physics that I find strongly convincing; according to our scientific knowledges, all chemical and biological processes (including cerebral processes) are caused by the electromagnetic interaction between subatomic particles such as electrons and protons. Quantum mechanics accounts for such interactions, as well as for the properties of subatomic particles. The point is that there is no trace of consciousness, sensations, emotions, etc. in the laws of quantum mechanics (as well as in all the laws of physcis). Consciousness is irriducible to the laws of physics, while all cerebral processes are. This is for me the most convincing argument against materialism (which identifies cerebral processes as the origin of consciousness) and in favour of the existence of the soul, as the unphysical and trascendent principle necessary for the existence of our consciousness. Since our soul cannot have a physical origin, it can only be created directly by God. The existence of God is a necessary condition for the existence of our soul, as well as for the existence of us as conscious beings.
