The concept of a "planet" being the God of heaven is a misconception stemming from the personification of celestial bodies in ancient mythology. In Roman mythology, Jupiter, the largest planet in our solar system, was considered the king of the gods and the god of the sky and thunder. However, in modern times, no planet is considered a deity.
The idea of a God residing in a specific planet is a human projection based on the limitations of our understanding of the cosmos. Many ancient cultures assigned divine roles to celestial bodies, but these were primarily symbolic representations of their beliefs and values.
