This is the origin of the Legend?
This is a prequel to Ocarina of Time, so I am thinking this is the 'true story' behind the LEGEND.
Considering a 'legend' is a story/explanation of an event from long ago. 'Legends' usually change minor or major details of a true event in history.
Even though this is a prequel to Ocarina of Time, I see many refrences to Ocarina, Majora's Mask, Wind Waker, Twilight Princess and all the other games. So could this be the true story of Link and Zelda, and people started telling this story, and over time, some details were left out or exaggerated...which lead to different stories. Which explains the other 'Legends of Zelda' games.
