Version 0.1
Possible theistic systems:
-Atheism: no god. Zero gods.
-Monotheism: one god (usually a creator).
--Deism (subset of monotheism): one god that created the Universe but doesn't interact with it.
-Pantheism: everything is god.
-Duotheism: two gods.
-Polytheism: multiple gods.
--(Subset of polytheism): Henotheism: only one god is worshipped, but the existence of other gods is not denied.
--Practical atheism/ideological monotheism: belief in one god, but without worshipping him/her.
--Practical atheism/idelogical polytheism: belief in multiple gods, but without worshipping any of them.
-Primordial monotheism/current atheism: there was one god that died while creating the Universe (possibly creating the Universe was a suicide or self-sacrifice). So there was a creator god, but (s)he no longer exists now. It's a mix between monotheism and atheism.
-Non-creator monotheism: there is only one god, but that god is not the creator of the Universe. It has one thing in common with atheism: the Universe has natural causes, but differs from atheism by saying a god exists.
-Non-creator polytheism: there are multiple gods, but none of them created the Universe.
-Every living being is each a (separate) god or goddess.
-Every living being is part of one god (which is the sum of all living beings)
-There is a god or a goddess inside of us, but they are not part of us, and we are not gods.
-There is a god or a goddess inside of us, and they are part of us, but we are not gods.
-There are three gods that created the Universe: the primordial substance god, the designer god, and the architect god. The primordial substance god killed himself/herself, so his/her dead body became the primordial substance of the Universe, then the designer god decides how the Universe will be, and the architect god takes the primordial substance and models it according to the designer god's wishes.
-Each person becomes a part of a certain god or goddess after death, which god or goddess, depends on that person's behavior and/or other circumstances.
-Humans will become gods after billions of years of evolution.
-Pandeism: god became the Universe
-Gods are psychological archetypes
-Humans create the gods (i.e. gods start existing when humans "make them up")
-Humans discover the gods (i.e. gods already existed even before humans "made them up", it's a discovery of the divine, not a creation)
-Humans make up the gods (i.e. gods didn't exist either before or after humans "made them up")
-Inclusive monotheism (there is one god, and every god is part of that one god)
-Exclusive monotheism (there is one god, and the other gods either:
--Are not gods)
--Do not exist at all)
-Inclusive duotheism (there are two gods, and every god is part of one of those two gods... some forms of Wicca are like this)
-Exclusive duotheism (there are two gods, and other gods either are not gods, or do not exist at all)
-Bicreator duotheism: there are two gods and they both created the Universe
-Monocreator duotheism: there are two gods, one of those created the Universe, and the other one didn't.
-Non-creator duotheism: there are two gods, and none of them created the Universe.
--- Problem of good/evil ---
Atheism: there are no gods, so the question does not apply.
Triomni(benevolent) creator deity: problem of evil arises
Triomni(malevolent) creator deity: problem of good arises
Deism: no problem of good/evil, as the god of deism does not intervene or care about the creation
Polydeism: no problem of good/evil, since none of the gods of deism created the Universe as a whole, and therefore none of them could even have an interest in the Universe as a whole, even if they did intervene or care about their creation
Theism that postulates a god who killed itself in order to create the Universe (and therefore the Universe is God's dead body): depends if that god knew about the evil its dead body would contain, and/or whether that god was omnibenevolent/omnimalevolent, or morally ambivalent/indifferent.
Omniscient, omnipotent, morally ambivalent/indifferent creator deity: no problem of good/evil
Pantheism: depends if this deity as a whole has the triomni+(benevolent/malevolent) properties or not.
Panentheism: same as Pantheism.
Polytheism without divine creation: there are many gods, but none of them created the Universe (which either always existed, or had a natural cause, such as the Big Bang)
Divine creation by two gods: both are omniscient but not omnipotent, and one of them is omnibenevolent and the other is omnimalevolent. The conflict between the two deities causes some amount of good and some amount of evil in the world. Whether other gods exist can be "yes" or "no", it doesn't change the result.
Omniscient, omni(benevolent/malevolent) but not omnipotent creator deity: no problem of good/evil
Omnipotent, omni(benevolent/malevolent) but not omniscient creator deity: same as above
Omni(benevolent/malevolent) but neither omnipotent nor omniscient creator deity: same as above
(Not omnipotent) God's level of benevolence is affected by humans' behavior. Kindness and cruelty both send psychic energies to God and affect God's nature.
