Final answer:
Noah did not convince his father to return home. He followed God's instructions to build an ark and save his family from the flood.
Step-by-step explanation:
Noah did not convince his father to return home. The question seems to be based on a misconception. Noah's father, Lamech, died five years before Noah was born.
According to the Bible, Noah was instructed by God to build an ark to save himself, his family, and a pair of every living creature from a great flood.
Noah followed God's instructions, and it was through his obedience that he and his family were saved.
