We can see the Sahara we're standing on. It may be 93 million miles away, but we have shitloads of evidence that the Sun exists; just ask NASA/JPL.
And although it doesn't physically exist, we can see that rainbow after a rain shower, and the sun comes out.
Something that doesn't exist, but can be seen. If that alone - a Rainbow - doesn't completely annihilate the concept of the 'Spiritual'/'Supernatural', then the fact that Jesus lied: 'Do unto others as they do unto you': what had those moneylenders in the temple perasonally done to him, to justify his use of violence - whipping - against them, being the least of his, never mind your, problems, Mr. Crocoduck.
Now go eat your banana, Ray Cumfart. 'Truth'? There are tens of thousands of denominations of Christianity, each one claiming to have the 'Truth'; there are those that you're going to Hell for not accepting their 'Truth'.
When asked by Pilate 'What is Truth?', Jesus couldn't answer, so that alone destroys the whole concept of 'Truth'. And when not even the Bible itself is admissable as evidence in a court of law, i.e. Kitzmiller vs. Dover, (thus the defence being reduced to the pseudo-science of (Un)'Intelligent Design', Creationism by Stealth, then not even an 'open' mind will accept lies, otherwise, why didn't said defence just say 'Godidit?'), then the fact that Materialism/Secularism/Atheism holds all the aces in the grand 'Religion vs. Atheism' poker game - as in evidence - should tell you something.
...after all, what's stopping your so-called 'Omnipotent' God from doing a Morgan Freeman in the Jim Carrey film "Bruce Almighty, eh Ray...?!
Aye, and that's the entire debate-destroying rub, indeed. You lot are reduced to needing 'evidence', so what's happened to 'Faith'? Or do you know deep down that 'Faith' sounds just like FAIL, and ultimately, you cannot spell 'Belief' without the word LIE...?!
We Atheists have the evidence. We win. Every time [/Kitzmiller vs. Dover]. So-called subjective* 'Truth'? Pfft. Just the facts, ma'am. [/"Dragnet"]
*- 'What's True, is true for you'
-L. Ron Hubbard, Founder of $cientology
So just that quote alone destroys the concept of 'Truth'; 2+2=5, according to O'Brien, the Inner Party & Big Brother [/"1984"], otherwise you & all your ilk are forced to admit that $cientology is better than Christainity, David Miscavige is Jesus, and L. Ron Hubbard is superior to God.
