Final answer:
The cause of Menes' death after his 62-year reign is not definitively known, as ancient records commonly leave historical events such as royal deaths open to speculation and interpretation.
Step-by-step explanation:
The cause of Menes' death after his 62-year reign is shrouded in mystery and is not definitively known. None of the historical texts provided give us a clear indication of how Menes met his end. However, we do have historical narratives about the deaths of other leaders.
For example, Genghis Khan died under mysterious circumstances, possibly in battle, falling from his horse, or at the hands of a Tangut concubine, and he was buried in an unmarked grave according to the customs of his tribe. Another example is Alexander the Great, who after an arduous journey back to Babylon, succumbed to a combination of injuries, excessive drinking, and exhaustion.
The circumstances surrounding Tutankhamun's death also remain unclear, with various speculations suggesting a chariot accident, murder, or even a hippopotamus attack! Therefore, when approaching the subject of Menes' demise, it is important to recognize that ancient historical records often leave us with more questions than answers.
