You mentioned we don't have sufficient evidence, but let me ask you this: can any human create a trinity of trinities Space, Time, and Matter consisting of Space: 1D, 2D, and 3D; Time: Past, Present, and Future; and Matter: Electrons, Protons, and Neutrons?
You also mentioned the argument about what caused God. But let me tell you this: God is necesary instead of contingent. Think of it like a computer programer creating code on a compurer. The programer is necesary for the code to exist because if the programer didn't exist, the program couldn't be runned.

2) Cosmic "Fine-Tuning" shows that if any aspect of the fundamental constants of physics were fine tuned, life would be impossible. Religious world views along with cosmologists across agnostic and secular worldviewd widely acknowledge said truth.
