I think the evidence shows Jesus probably didn't exist, not that he didn't for certain. But even if he was a real man, people in this day and age follow all kinds of 'messiahs' and 'prophets'. Check youtube for videos on Sai Baba the 'miracle worker'- he has over a million followers! How easy would it have been for a Jesus to convince some that he was the son of a god?
The way these debates usually go (in my experience) is the believers try to give evidence or reason to believe in their god, and they are refuted every time. Then it comes down to 'faith', which is a concept so obviously flawed even the believers don't use faith in 99% of their lives- just for this god belief.
I do think the atheists have the upper hand.
Lesterd: There has to be belief, before there is dis belief.
Do you believe in walking living peanuts that roast in a little spaceship 2 miles from the sun? No? But to disbelieve that, you must have believed it at some point, surely?! Of course we don't need to believe something before we disbelieve it.
