Why can't odyssues just kill the Cyclopes

Cyclopes are like giants but Odysseus is a god so he can pretty much kill them

Because of Odysseus's clever thinking, Polyphemus shouts out that "Noman" has been trying to kill him. This leaves Polyphemus blind. This allows Odysseus and his men to escape because of Odysseus's different thinking skills. These different thinking skills allows Odysseus to flee from grave danger situations
