I am not an atheist. There may be some guiding hand which created and rules the universe, or it may be made of pure energy which coalesced into patterns of particles, which formed atoms, which combined to form elements, which over eons of time recombined and altered to form the millions of life forms that exist and have existed. I will not know for sure until I die and either meet my creator or return to my component parts to be used to form a new entity.
If I were sure that God, the Devil, Heaven and Hell were not created by man in his own image (good, bad, happiness, misery) then the God I would choose would be the one described by the carpenter of Nazareth - a wise, loving, forgiving, supportive father.
Not the God of the Old Testament - angry, jealous, vindictive, demanding attention and worship, sacrifice of possessions happiness and ambitions to his glory.
Not the God of the global church institutions, led by fallible humans who claim infallibility and impose arbitrary rules which ignore the basic needs of other humans and their earthly health and well-being while emphasising how rapturous they will be hereafter.
Not any religion which demands complete unquestioning obedience, and punishes even those who are not part of it for imagined slights.
Not those whose leaders expect their followers to hand over all their worldly wealth to keep the few in luxury in this life, in return for a promise to be spared the everlasting pains in the next.
Meanwhile I try to live reasonably well and not decry whatever others believe. Belief cannot be achieved by force of argument or by concentrating the will, though it may be nurtured by example. It is a product of internal forces within the personality of the believer.
