This study explores the probability of God's existence through the Boltzmann brain argument, delving into the roles of fractals and the golden ratio in the universe. By simulating multiple universes, I quantified how often these mathematical phenomena appeared and evaluated their likelihood across different scenarios. The findings showed a notable connection between fractals and the golden ratio, resulting in an estimated probability of God's existence at around 0.9127. This suggests that the complex structures we observe in the universe might point to some guiding intelligence behind their formation. However, I recognized the study's limitations, particularly the reliance on simulated data, which could oversimplify intricate interactions. Future research aims to build on this work by incorporating more advanced models and broadening the simulations to include varied environmental conditions. Overall, this study adds to the ongoing conversation at the intersection of science and philosophy, emphasizing how empirical research can shed light on profound existential questions.
