cofty, just as I don't expect to persuade you that Adam and Eve did exist, you can't persuade me of the inexistence of God, for it is impossible to prove the inexistance of something unless you first define such something. By "defining" it, you are already constructing its existence, even if by intelectual conjecture alone. So it's circular reasoning.
Faith in God comes primarily from inside yourself, and isn't dependant on the world outside you. Naturally, the more evidence you perceive as proving God's existance, the more solid is such faith, but it's not an absolute requirement.
