The concept of creatio ex nihilo, traditionally understood as creation from nothing, requires careful reexamination of what we mean by 'nothing.' While common interpretations suggest creation from the complete absence of reality, this work argues for a more nuanced understanding more aligned with Leibniz's ontology, and distinguishes between physical nothingness and metaphysical reality. This distinction proves crucial for developing a coherent understanding of how the universe could have emerged and argues that universe is fundamentally a mathematical entity.
