No, Zeus is not alive, because he is a mythological figure, specifically a god from ancient Greek mythology.
While Zeus, as a deity in Greek mythology, is considered immortal within the context of those beliefs, the concept of "alive" requires a physical existence. Mythological figures like Zeus exist within the realm of stories, legends, and cultural traditions, not as tangible beings in the real world.
Therefore, while he plays a significant role in mythology and continues to be a part of our cultural consciousness, Zeus does not exist in a way that we could consider him "alive" in a literal sense. He is a character in a vast and enduring body of stories.
