The Noah's ark story is allegorical. The flood waters symbolize the chaos that brings forth rebirth. It is the earth cleansing itself...balancing itself. The bible attributes the flood to God's wrath because of mankind's sin.

Many cultures have flood stories, many dating before the bible:

Southwest Tanzania (Rukwa Region):

The rivers began flooding. God told two men to go into a ship, taking with them all sorts of seed and animals. The flood rose, covering the mountains. Later, to check whether the waters had dried up, the man sent out a dove, and it came back to the ship. He waited and sent out a hawk, which did not return because the waters had dried. The men then disembarked with the animals and seeds. [Gaster, pp. 120-121]

Babylonian:

Three times (every 1200 years), the gods were distressed by the disturbance from human overpopulation. The gods dealt with the problem first by plague, then by famine. Both times, the god Enki advised men to bribe the god causing the problem. The third time, Enlil advised the gods to destroy all humans with a flood, but Enki had Atrahasis build an ark and so escape. Also on the boat were cattle, wild animals and birds, and Atrahasis' family. When the storm came, Atrahasis sealed the door with bitumen and cut the boat's rope. The storm god Adad raged, turning the day black. After the seven-day flood, the gods regretted their action. Atrahasis made an offering to them, at which the gods gathered like flies, and Enki established barren women and stillbirth to avoid the problem in the future. [Dalley, pp. 23-35]

Sumerian:

The gods had decided to destroy mankind. The god Enlil warned the priest-king Ziusudra ("Long of Life") of the coming flood by speaking to a wall while Ziusudra listened at the side. He was instructed to build a great ship and carry beasts and birds upon it. Violent winds came, and a flood of rain covered the earth for seven days and nights. Then Ziusudra opened a window in the large boat, allowing sunlight to enter, and he prostrated himself before the sun-god Utu. After landing, he sacrificed a sheep and an ox and bowed before Anu and Enlil. For protecting the animals and the seed of mankind, he was granted eternal life and taken to the country of Dilmun, where the sun rises. [Hammerly-Dupuy, p. 56; Heidel, pp. 102-106]

Yakima Indians (Washington):

In early times, many people had gone to war with other tribes; even medicine men had killed people. But there were still some good people. One of the good men heard from the Land Above that a big water was coming. He told the other good people, and they decided they would make a dugout boat from the largest cedar they could find. Soon after the canoe was finished, the flood came, filling the valleys and covering the mountains. The bad people were drowned; the good people were saved in the boat. We don't know how long the flood stayed. The canoe came down where it was built and can still be seen on the east side of Toppenish Ridge. The earth will be destroyed by another flood if people do wrong a second time. [Clark, p. 45]

Islamic:
Allah sent Noah to warn the people to serve none but Allah, but most of them would not listen. They challenged Noah to make good his threats and mocked him when, under Allah's inspiration, he built a ship. Allah told Noah not to speak to Him on behalf of wrongdoers; they would be drowned. In time, water gushed from underground and fell from the sky. Noah loaded onto his ship pairs of all kinds, his household, and those few who believed. One of Noah's sons didn't believe and said he would seek safety in the mountains. He was among the drowned. The ship sailed amid great waves. Allah commanded the earth to swallow the water and the sky to clear, and the ship came to rest on Al-Judi. Noah complained to Allah for taking his son. Allah admonished that the son was an evildoer and not of Noah's household, and Noah prayed for forgiveness. Allah told Noah to go with blessings on him and on some nations that will arise from those with him. [Koran 11:25-48]
