Who is the protagonist of the original Assassin's Creed game released in 2007?

Altaïr Ibn-La'Ahad is the protagonist of the original Assassin's Creed game released in 2007.

Altaïr is a Syrian Assassin operating during the Third Crusade. The game follows his fall from grace after a reckless mission, followed by a series of assignments that restore his rank and reveal a wider conspiracy involving the Templars and the Pieces of Eden.

His story is experienced through the Animus, a device that lets Desmond Miles relive ancestral memories. This framing device connects the medieval narrative to a modern-day science-fiction storyline and became a defining feature of the series.

Altaïr is sometimes confused with Ezio Auditore, the lead character of Assassin's Creed II and its two direct follow-ups. Ezio's Italian Renaissance setting and longer character arc made him more familiar to many players, but he is not the original game's protagonist.
