I am an orthodox Christian, ask me a question!

[Tiberius]

So let's call it a post-supposition after seemingly not finding evidence; then when you bring that post-supposition into an argument with a theist (me) who has the post-supposition that there is evidence, it becomes a presupposition through which the theistic evidence and post-suppositions are viewed with.

No, my post-supposition after looking at the evidence is not brought into arguments containing new evidence. That would be a foolish way to look at things. If you come up with a new argument that shows evidence for God (and doesn't have other explanations) then you have evidence that is good enough for me.
