I recommend the Five Ways of Proving the Existence of God of Saint Thomas Aquinas. This is a philosophical answer to the question, a very old question. and about recursive questioning about creating, Saint Augustine answered this problem, God is eternal and doesn't exist the time before him, He created the time, thinking about a time before the time is impossible. please I recommend that you read and analyze these answers, the journey is very deeply and clearing.
Peace and God bless you 🙏
I was gonna recommend Aquinas as well with regard to this particular issue.
An abstract God is an empty God, that is the same to tell theres no God in reality.
Those rely on linguistics only, no empirical proof, like axiomas in mathematics.
It is impossible to explain the origin of the material world from the material world. The origin of the universe is out of the universe. only the philosophy and metaphysics can explain this, is a logical answer. you don't expect that mathematics can resolve all questions, with an equation, because this is out of mathematics scope. This is like trying to resolve a physical problem with philosophy. it doesn't make sense.
