What is the difference between epic of Gilgamesh and Noah and the ark?

According to the Old Testament, Noah came before Moses. He lived to be about 950 years old, and built an ark to save his family and two of every animal (male and female) when he was 600. His wife was Naamah, and his children were Shem, Ham, and Japeth. Noah was a holy man in a time of wickedness, so he was saved and told by God to repopulate the earth after the wicked were destroyed in the flood.

Moses came much later. Unlike Noah, he was basically royalty to the Egyptian people, as his adopted mother was the Pharaoh's daughter. Though old, Moses didn't get to be nearly as old as Noah. He died around 120. Like Noah, he took his people away from the wicked, but the wicked weren't destroyed from the earth. Moses wandered with the "Children of Israel" for 40 years in the wilderness and received the 10 Commandments when he talked to the Lord in the Burning Bush.

Summary: Different time, different ages, different race, different situations and prosperity.
