"God does not exist" when in fact He does"
'Fact'. You keep using that word. I do not think it means what you think it means.
And I see no 'Facts' in that book of fairytales you call the Bible, to see any extraordinary evidence to prove - to our satisfaction - that your so-called 'God' exists. Because if a mere 'book' says that something exists because it says it exists, then I can enter the cupboard I keep my clothes in and emerge out the other side into another world and meet a talking lion, because the book "The Lion, The Witch, and the Wardrobe" says so - and CS Lewis was a Christian.
PROTIP: 'Bible' comes from the Greek word 'Biblios' meaning 'Book'. Ergo, all books - even the manga I have on my bookshelves - are Bibles, and are therefore 'Truth' too. Q.E. and D., bitch.
...and the books on Mathematics, Physics, Biology and Astronomy/Cosmology are by definition 'Bibles' too. You said it, I didn't, with your insistence that 'The Bible is Truth' and all that jazz.
At least a book on Mathematics, Physics, Biology (even Evolution), and Astronomy/Cosmology (even the Big Bang) is fact, because it has the evidence to back up, and thus prove it is Fact. And the only possible way you can prove the existence of your 'God' - to our satisfaction - is to make him appear before us, in hard, solid, physical form (and that's God himself, not Jesus) that can be seen, heard & touched, and for him to prove he is what he says he is - again, to our satisfaction - by demonstrations of his power. And if (in my case) that means he must do whatever I say in perpetuity, then that's the condition, and it's not up for negotiation.
...now, can you do that: use extraordinary evidence to prove your extraordinary claim(s), fundies? Because if you can't, then it only serves to prove that your 'God' doesn't exist; PROTIP: in making the initial claim, therefore the onus is on you to prove such - to our satisfaction.
'Burden of Proof' and all that jazz, bucko. No evidencee, no acceptee.
