I can undermine the "evidence" for existance to the point it is foolish to think otherwise.
You paste lies on things by claiming what was written by people ignorant of what we know today explains the world. To look at the beauty of the universe and go 'Ah, God did that, look this book tells me so' is to paste lies on that beauty to me.
Well, the people that actually write things tend to be called authors, so it was written by men over a period of hundred of years, has been translated into language upon language, has pieces removed from it and added to it over those years, and claims things that are now patent bollocks.
I don't see why some imaginary friend being named by people that believe it exists being called 'causes to become' is evidence for anything other nutjobs who could speak Hebrew. It certainly doesn't mean he exists.
I can do what humans do and look at the logical ends of evidence and say yeah, barring miracles, it's a lie. Certainly, lots and lots of the Bible is lies, proven lies. Why believe the rest that has even a modicum of chance of being truthful?
No, they don't swallow bollocks, they're obviously intelligent enough. I tend to be an antitheist because, well... it's all bullshit to my mind and I took the step further than just saying 'Nah, I don't believe it, but who knows', into 'This is clearly arse gravy and we're beyond this now, lets rid ourselves of this evil for simple people, and go on and be something better now we know better'.
