What specific evidence would people require to believe in God's existence?

Before we even get to that point, I woudl like to have a clear definition about what God is.There seems to be a big disagreement about what God is/did/does.For the 'personal' type of god that is prevelant amoung the christians, I would hve to see a mechanism by which God intervenes.FOr the deist god , where the concept is god 'wound up the universe' and then let it on it's merry way, I would need to see evidence on the existance of an intelligence OUTSIDE the universe that can manipulate quantum flucuations...

Snacks huh?Is that what God wants to use for our souls.Could you say that it is 'soul food'?
