Here's one secularist-humanist standpoint, neither atheistic, agnostic or deist. One has to subscribe to evolution for it to work, however. Take with salt, as needed.
1. Big bang.
2. Condensation of matter from pure energy.
3. Formation of physical laws, including Newton's I-III.
4. Newton's II causes autocatakinetics (self-assembling structure)
5. Autocatakinetics causes biologic evolution.
6. Biologic evolution results in sentient, perception-response life forms.
7. The complexity of any given life form is subject to its available resources, plus parameters.
8. If humans evolved on one planet, what would be the complexity of a life form that had orders of magnitudes more available resource?
9. A HYPOTHETICAL life form sufficiently advanced COULD HAVE appeared to our human ancestors as "infinite", "eternal", Alpha and Omega, superlative, omniscient, omnipotent, omnipresent, ad infinitum.
10. There's nothing in the accepted validity of biologic evolution that precludes life forms growing into the maximum potential of their environments.
11. The universe is at most 15 billion years old, at least 26 billion light years across, and comprised of at least trillions of galaxies. If a HYPOTHETICAL 'god' life form arose, it has had the means (energy and matter), motive (Newton's II and autocatakinetics), and opportunity (at most ~14 billion years, since matter distilled into recognizable form at 1 billion years)
12. Ergo, the age and mass of the universe could hypothetically support a life form that humans would interpret as a "god".
13. A HYPOTHETICAL god existing in our space-time in no way invokes some kind of craven, cowardly, timid, fearful, servile, subservient, slavish, compliant, deferential "moral obligation" to listen to its statements.
14. Evolutionary self-preservation might encourage a life form to sacrifice freedom through the construct of religion, but religion itself, i.e., the idea that we OWE some superhuman entity, is a complete fiction.
15. A HYPOTHETICAL god with sufficient power to kick our ass back to eucaryotes does not, through some axiom of "might makes right", deserve slavish obedience or deference. Evolution is all about extinction.
16. It may be that human independence in its own evolutionary experiment is worth far more than self-preservation through slavery. "Better to reign in Hell than serve in Heav'n." -Milton
