Why your exsistence is more worthless than you previousy thought it was.

[Mudhammam]

The universe would be exactly the same either way though there's clearly a lot of fine tuning and complexity of structure and everything balanced on a knife edge to allow complex organic forms to generate themselves on suitable balls of rock. All this if you're going to think logically about it suggests a purpose made creation, purpose implies intelligence therefore a purposeful creator, pure logic. You just have to go where all the evidence takes you regardless of what you would ideally like.

So by your "pure logic," the fact that intelligent beings exist who interpret the Universe and try to form languages to describe its "structure," this means an even Bigger Inteligent Being exists! And needs no explanation! Because you said do! Pure logic!

You don't need any stories to figure out the cause of the universe it's fairly self explanatory, though will need some revelation to know anything about this purposeful creator intelligence. I could provide you with some.

What purposeful creator intelligence? You mean human beings? Yeah, Darwin discovered the way to explain that through observation. It's called natural selection.
