Rationality does not cover the unknown
I have no idea what this is supposed to mean. It's gobbledegook.
Something that is unknown is, er, unknown.
In order to make discoveries, we have to begin with viable questions. That's the first mistake theists make....to assume that their questions make sense & therefore have a potential answer.
"Who created the universe" is a good example. "What caused the universe" is another. There's no way to know yet whether these are even good questions to ask.
Theists assume they are and then make up the answer. And the answer is usually suitably wishy-washy and meaningless and, most important, impossible to falsify. Bizarrely, they'll then use this important failing in their hypothesis as some kind of evidence that it's sound.
"Ah....you can't prove God doesn't exist" is quite the stupidest thing anyone can ever say.
And your understanding of how science works, Spinnaker has not improved one iota in spute of the fact that you have had the simplest explanations explaiane to you again and again and again.
