When it comes to religion, the most popular views are monotheism & polytheism. However, they are not completely the same. Each religion has its advantages and disadvantages. The main difference between the religions is how they view the world. Monotheism tends be more peaceful, and everyone can worship the same god. This helps to avoid conflicts between different civilizations.
Mythology
The difference in monotheistic and multitheistic mythologies doesn't lie in the nature or representation of the gods. In polytheistic mythology, the gods are viewed as the products of long-term processes of interaction among the gods.

Twelve Olympian gods were present in ancient Greece. They included Zeus and Hera. Demeter, Apollo and Artemis were also gods. Each god served a specific purpose, including providing sustenance. Nevertheless, there were a few exceptions, like Hades who lived the underworld.
Morality
Polytheistic and monotheistic societies differ largely in their views of morality. Monotheism tends toward absolute values, while polytheism allows relative morality. Although the two approaches are quite different, they both emphasize individual responsibility.
Monotheistic religions generally elevate one god into a supreme place. Then they treat all other gods as manifestations or the supreme god. They become monotheistic in this manner.
Religion
Monotheism and polytheism are two different approaches to religion. Monotheists believe that there is one divine creator. Polytheists, on the other hand, believe in the existence of multiple deities. Both sides claim to be right but disagree about what makes a religion true.

While polytheism is believed to have led to monotheism, the reasons for its rise are not clear. Monotheism is a result of one of two processes, according to modern religious philosophers.
