What I do not see is any logical necessity to go beyond that, especially if doing so requires the invocation of mythical beings, like an eternal god.
Because the evidence and logic requires it, the argument for which I have already presented, and which I will present again in this post.
Besides, invoking god just brings us back to the conundrum of infinite regression. The only way to solve that is to say that god came from nothing.
No. "God" is the term that refers to the "final cause", the eternal being that is the source of all causation. It invokes no "infinite regression" or "causation from nothing" because it is the eternal uncaused cause.

deliberate being is required to be the causeless cause, or else how did it generate the universe? The only useful description of a causeless cause that creates things is that it is an intentional agency - or else one is back to irrational explanations of origin.
Furthermore, that the universe is so orderly that continuous, living beings can exist with rational minds which can deliberately discern truthful statement about the world to the point of being able to manipulate materials and forces to generate virtually infinite amounts of specified complex functionality, directly implicates a final cause, a purpose, what Aristotle called the "good" of all things.
A purposeless, happenstance universe cannot generate an encyclopedia, a computer, a space shuttle, a battleship. There must be incredible heirarchical order imposed from a systems management and development perspective in order for everything to exist in just the right states (strong anthropic argument) so that anything cohesive and significant can exist, much less self-replicating, cognizant life that can reason and generate marvels of entropy-defying order and complexity and functionality.
This necessarily means - logically - that the final cause that generated the universe did so with deliberate purpose from a systems development perspective. IOW, there had to be a teleological final goal or purpose in mind.
The conclusion is: the final cause must have been an eternal, uncaused, deliberate, intelligent agency that created the universe for a purpose. IMO, that description meets the fundamental requirements for the term "god" to be an appropriate label.
Would it not be more logical to leave mythical gods out of this and just say that the universe came from nothing?
If you wish to argue that the idea that something can come from nothing is rational, we don't have anything left to debate, because things can just pop into existence from nothing and rational observation and orderly inference based on cause and effect is destroyed.
