How so?I think you mean to say that YOU lack the knowledge to name anything else.Or that we lack knowledge.Inflation theory is the leading cosmological model which explains how space and time were created through a quantum tunneling event. An event which occurred per the laws of quantum mechanics and conservation of energy. Which means those laws were in place before space and time which means those laws were the first cause but still doesn't address the source or first cause of those laws. The only solution to that dilemma is something which is eternal and unchanging.
My position is that the only solution which exists for the first cause conundrum is something which is eternal and unchanging.
Not if you follow the ABG theory.
