Are there any non-scientific non-religious cosmological theories proposed in recent times? I looked at various cosmological theories proposed and I only see scientific ones (ex: Machian universe), and also religious ones, but none of them seem to have come from philosophers. Is there any philosopher who proposed a new cosmological theory in recent times? I don't mind older theories as long as it was proposed after 1900.
Consider the Elephantidae Testudinata Theory of creation:
About 15 billion years ago, after eternally climbing an infinitely deep stack of turtles, an elephant eventually reached the top. The enormity of that accomplishment caused our universe to spring into being.
This is a non-scientific cosmology theory, because there is no physical means by which mankind can prove or disprove it.
This is a non-religious cosmology theory, because there was no supernatural revelation of it to mankind.
Except for a bit of plagiarism, it is entirely a product of my own imagination, and I make no claim that it is true or divinely inspired.
Other than similar instances of fantasy/fiction, I don't think there can be "any non-scientific non-religious cosmology theories proposed in recent times".
