OK, so you are proposing that the universe is infinitely old and has always existed in physical form as we experience it today. After all, we have based our human mathematics on Universal values and functions.A Universe from nothing is never possible. Nothing as being defined as No physical properties , No physical dimensions , length , width and depth , nor movements and can never evolve .

Except at Planck scale, where physics no longer apply, because things that small are no longer physical patterns (matter), but abstract dynamical values. Read up on CDT (Causal Dynamical Triangulation)

Causal dynamical triangulation(abbreviated asCDT) theorized by Renate Loll, Jan Ambjørn and Jerzy Jurkiewicz, and popularized by Fotini Markopoulou and Lee Smolin, is an approach to quantum gravity that like loop quantum gravity is background independent.

https://en.wikipedia.org/wiki/Causal_dynamical_triangulationThis means that it does not assume any pre-existing arena (dimensional space), but rather attempts to show how the spacetime fabric itself evolves.

**Quantum Gravity from Causal Dynamical Triangulations: A Review ,**R. Loll, [Submitted on 21 May 2019]

https://arxiv.org/abs/1905.08669This topical review gives a comprehensive overview and assessment of recent results in Causal Dynamical Triangulations (CDT), a modern formulation of lattice gravity, whose aim is to obtain a theory of quantum gravity nonperturbatively from a scaling limit of the lattice-regularized theory. In this manifestly diffeomorphism-invariant approach one has direct, computational access to a Planckian spacetime regime, which is explored with the help of invariant quantum observables. During the last few years, there have been numerous new and important developments and insights concerning the theory's phase structure, the roles of time, causality, diffeomorphisms and global topology, the application of renormalization group methods and new observables. We will focus on these new results, primarily in four spacetime dimensions, and discuss some of their geometric and physical implications.
