God was created in our image.
Gods were created in two ways. One was to merge the thousands of spirits that invisibly moved things into a single One God. In that way, it demanded some personalization of that God. God may have been invented by ancient shamans and War Lords. Naturally, their template was the personality and appearance of a Neolithic or Bronze Age warlord.
As a result, the Celtic God Dagda was a giant human who had sex with a human virgin to produce Lugh the Sun God. Each had human characteristics. Dagda even had a grandson, Cuchullain, after his son Lugh impregnated another human virgin.
Then we see this echoed in Zeus, Ahura Mazda, Brahma, Jupiter, Odin, JHWY, and the post-deification Jesus. Allah is the only one that I think is not anthropomorphised any more than having magical powers and seeks vengeance. His appearance is never described. This makes Islam the only real Monotheism that is in fact Theism. All of the others are merely Idolatries.
The most obvious aspect of Godly anthropomorphism is the myth of a cosmic creator eternally old, impregnating a human. That implies that God is genetically more than 99.9% DNA compatible with humans.
God exists but not as some Galactic or Cosmos conscious being. God exists in the minds of believers. He is male because those who created him as a mental concept designed him on their local warlords or kings. He exists in a complex of brain circuits heavily concentrated in the Limbic Lobe but with multiple connections to many other brain association areas. Most Christians have a mental concept of Jesus. This Jesus can be seen by the believe in hallucinations such as Temporal Lobe Seizures (Partial Complex). We see different Jesus’ dependent on our individual circuitry. Europeans and Americans see a North European blond haired or brown haired, blue eyes and Nordic facial features. Ethiopians see him as a black man with dark brown eyes. A few see him as a Palestinian Semite/Jew, short and stocky, tan skinned, semitic nose, black hair (probably curly).
