Show me proof of the existence of the number Pi.

Oh, it's irrational! You can't write it down, even if you have a million years and can type at 400cpm.

Am I splitting hairs here? Trying to break down something atomic?

Anthropomorphising principles is childs' play. Understanding what infinity means precludes such naive models.

People do confuse things though. Most people talk about something that is more like the ideal of humanity, as being God. If that's what made the universe, then it makes no sense. Plenty of evidence of what seems like disinterested impartiality, that invalidates the model of a man-like thing being the source of reality, even the "ideal".

Science fans are all following the atheist and materialist models popularised by media, but real scientists who actually understand the deep math that is visible already just from our primitve tools believes in some kind of intelligent origin to the universe because of it's incredible elegance and the simple, yet combinatorially impossible to calculate nature of everything.

Since you are a materialist, explain to me what a "principle" is, and where to go grasp hold of one.

Yes, let's start with this principle called "empiricism". This supposed evidence. What if it's entirely intangible, a mere concept, a pattern of cause and effect?
