What were signs that Odysseus was still alive?

In Homer's "Odyssey," signs that Odysseus was still alive included the mysterious prophecies of seers like Teiresias, who suggested that he would return home. Additionally, the unusual behavior of his son Telemachus, who embarked on a journey to seek news of his father, hinted at the belief that Odysseus might still be alive. Furthermore, the gods, particularly Athena, often intervened on Odysseus's behalf, signaling his enduring existence and favor in the divine realm.
