The description of some cosmologies are very intricate and involved? Why might a culture have multiple layers and sections?

The majority of the universe's origin stories were created in the pre-scientific era by different religious traditions in an effort to allay people's existential anxieties regarding things like how the universe came to be, what it's all about, life after death, and where I fit in it.

Religious leaders and philosophers, for the most part, "made up cosmological stories" that people could believe based on their own historical background, prevalent religious beliefs, and cultural practices. This eased people's minds so they could move on from contemplating life's big questions to cultivating their crops or whatever!

Beyond their historical cultural significance, these theological and culturally derived cosmological explanations should be considered fascinating myths specific to particular cultures, but not equally plausible theories or facts.

The Big Bang, the current cosmological theory explaining how the universe came into being, is supported by hard scientific data, verified experiments, and observations rather than by tales or beliefs.

Cultures may have complex cosmologies with multiple layers and sections to encapsulate diverse aspects of existence, including origins, morality, and the afterlife. This complexity often arises from the need to address various facets of human experience and provide a comprehensive framework for understanding the universe.
