Reasons why the evidence supports religion as a purely social phenomena supported by social conditioning rather than their actually being a God/gods who have brought about the various faiths.
Scientific: Theist propositions are in conflict with science and its reasoned methods. The most significant of these conflicts are those of God the creator and that though God is of the ethereal realm, He can affect the material realm.
Lack of agreement: This entails a lack of foundation upon which their premises are derived.
Lack of evidence: There is no museum quality evidence show the existence of any of the popular Gods, evidence which would make all right reasoning people agree that there is a god.
Anthropological: There is an evolution of religions. For example the Hebrew faith today is much different than that in the 5th century B.C. when the works which now comprise the Pentateuch were given special status by the Hebrews.
Ungodly god: All popular religions portray their gods in temperament and in actions as being quite like man with human emotions such as anger and jealousy, and thus not very god-like.
Ungodly demands: They have their gods requiring behavior of man that would not be required by a god; namely, building ornate temples, the services, the prayers, the chanting, and various other acts claimed to be pleasing to their gods. Such activities are what one would expect of priest to require of their followers.
Ungodly actions by God: They have their gods doing ungodly things like partaking in or affecting the outcome of battles, striking people down, having a hell for non-believers, heretics, and other bad people, bringing about natural disasters, and diseases.
False history: Their accounts of history in the sacred writings have numerous conflicts with the archaeological evidence. A system which will deceive for the sake of benefits is not worthy of respect.
Uninspired inspired writings: Their conception of events in the sacred writings is what we would expect of a pre-scientific people. They have demon possessing people, witches, their god causing diseases and natural disasters, deciding which side would win a battle, striking people down, and so on.
Conflicts with reason: Reason creates expectations about what a long-lived, super-intelligent being would be like and require of man, but the portrayal in the sacred writings is in conflict with these expectations.
God the creator a fiction: Science and evolution account sufficiently for the state of the universe. There is no need to add an hypothesis of a god the creator to this explanation, especially consider that we know nothing about the god or how such god could create anything, let alone everything. Moreover, the conditions of the world and universe (harm and vastness) strongly support the denial of god being the creator.
Absurd claims: They claim that their god has certain properties, but these properties (omnipotence, omniscience, and perfect beneficence) are not possible, therefore there could not be such a god.
Sphere of god is imaginary: To claim that god is transcendental and incorporeal, thus beyond the material realm is to place their god beyond in the realm of imagination. To invent a category of transcendental, capable of existing in the spirit realm and the material realm doesn’t entail that there is such a being, or that there is a spiritual realm.
Harm: Religions have promoted wars, torture, repression of liberties, repression of natural sexual behavior, received a dole improvidently spent, and supported the class society with its exploitation of the lower classes. They have filled the mind with nonsense and have been a force for darkness.
False and pernicious morality: By holding that the pleasures of coitus is sinful, except when done within the confines of marriage and by considering it better to serve the church than to serve mankind, the followers of Yahweh have promulgated a false morality.
That the world today is much different than the world of the scriptures: Theirs was a world full of demons, gods, prophets and miracles. For most people there are today no demons, other gods, prophets, and few miracles.
The scriptures appears to be the product of priest rather than the inspiration of a god: The science of their scriptures is false; their recreation of the earliest past including conquests of the Levant go unsupported; and their wisdom is but homilies.
The most ancient portions of the Old Testament are every bit as primitive as the pagan pantheon of Hesiod and Homer: Yahweh had a consort, Asherah, a collection of guards (Behemoths, Cherubs, Rahabs, Seraphs, levithans) and a counselor Satan.
Not a Divinely inspired book: Assuming the Judeo-Christian position of the divine involvement in the production of the Old Testament, then all these passages must be taken at face value.
