Problems understanding naturalistically the beginning of the universe

[robvalue]

Here's a very simple possible explanation:

This reality is a manifestation of a process in another reality. This could be a computer program, a brain, or whatever. It's some sort of "realisation" of an emergent property.

Crucially, there's no reason to think any intelligent beings in that reality have any idea that this manifestation has occured. How exactly would you know if your computer program manifested itself, with parts of it becoming "self aware"? Or if your dreams manifested somewhere?

There's no reason to pile on loads of extra assumptions on top of this, like:

-It was caused directly by an intelligent being
-The being was aware of the manifestation
-The being cares about the manifestation
-The being is very concerned with the activities of a particular group of organisms on a particular rock somewhere in the middle of the manifestation
-The being interacts with this manifestation
-The being has amazing powers which apply not just when interacting with this manifestation, but independent from it
-This being is the final end-all, and isn't itself a manifestation
-This being intends to further manifest you outside of this reality, into other realities, based on your actions
-This being doesn't want you wanking or letting gay people marry

And so on.
