People almost invariably arrive at their beliefs not on the basis of proof but on the basis of what they find attractive. And then they go looking for reasons to substantiate their belief. This applies to one’s ‘rejection of’ the existence of God (as you appear to have), as well as one’s ‘belief in’ the existence of God (which I definitely do have).
A lack of conviction in the existence of a God is justified by an absence of evidence for the existence of a God.
