Why did Voldemort want to kill Harry's parents in the first place? What really happened when they died?
Why did Harry survive the attack when his parents didn't?
There are several theories about why Harry survived the attack, but the most popular one is that his mother sacrificed herself to save him. Voldemort had given Lily a chance to step aside, but she refused, knowing that it would cost her life. Her sacrificial love left a powerful protection on Harry, which ultimately saved him.
