@Smiddy - you're right - there is no evidence for the existence of God.
But science cannot really comment one way or the other re the existence of God. How would scientists go about collecting data for a being that is meant to be invisible and which lives in a different 'world' (heaven)?
It's up to religious people to establish God's existence, something they haven't done.
Re creation/intelligent design - it is illogical to believe in this because all the evidence suggests humans evolved from a type of ape at least 200,000 years ago. So we can say with some certainty that the Adam and Eve story is bullshit, but not necessarily the existence of God.
