I found one paper in which the author writes some non-traditional argument for the existence of God, which can be summarized into the following categories:
- Metaphysical argument
- Nomological argument
- Axiological argument
- Noological argument
- Linguistic argument
- Anthropological argument
- Meta‐argument argument
In addition, a political argument for God's existence has been proposed:
Recently argument from beauty developed which is a much-neglected argument, and the author argues that the existence of God can best explain it.
Javad Taheri proposes Argument from unnaturalness of necessity for the existence of God:
Katherin Rogers argues that certainty indicates God and provide evidence for them:
Someone who is not powerfully committed to the non-existence of God, though, granting that we sometimes do have strongly certain beliefs about necessary propositions, ought to conclude that this provides some evidence for God.
Chaotic unpredictability, emergent property, and fine-tuning may show that physical reality does not behave as just happened to be, but works under the direction of God, as scripture like Bhagavad Gita says:
This material nature is working under My direction, O son of Kunti, and it is producing all moving and unmoving beings.
One author collected arguments for the existence of God, from which some are:

Edward Feser proposes five arguments in the book "Five proofs for the existence of God":
Professor Feser shows that if you believe any of the following propositions, you should also believe that God exists:
- Change is real.
- The things we see, experience, and interact with are made up of parts.
- Abstract objects, such as universals, numbers, propositions, and possible worlds exist.
- The things we see have distinct essences and existences.
- The principle of sufficient reason is true.
