Many people tell stories about big floods. 

Many people tell stories about great floods. 
These stories say a lot of water covered the land. Some say gods sent the water to clean the world. 
A hero often builds a big boat to stay safe. In one story, a man named Noah builds an ark. He brings animals inside to save them.
Other stories come from far away. Some are from Greece or India. Some are from North America.
These stories are very old. They help us learn how people thought long ago.
Many cultures tell stories about a great flood. These are called flood myths. In these stories, a huge amount of water covers the land. 
Often, gods send the water. Some stories say the gods want to clean the world. In the Bible, a man named Noah builds a big boat called an ark. He stays safe with his family and many animals. 
Other stories come from different places. In Greece, a man named Deucalion builds an ark to survive. In India, a man named Manu is warned to build a boat. In North America, the Blackfeet people have a story about a flood on a mountain. 
Why do so many people tell these stories? Some think real floods inspired them. For example, sea levels rose a long time ago. Other people found seashells high up on mountains. This might have made them wonder about deep water. Some even think a giant wave from a space rock caused them. We are still learning about these old ideas.
A flood myth is a story about a huge amount of water covering the earth. 

In many of these tales, a hero receives a secret warning. In the Mesopotamian story, the god Enki warns a priest named Atrahasis. He gives him special instructions to build a boat to survive. The Atrahasis family survives the flood to keep humanity going. Another famous story is from the Hebrew Bible. The god Yahweh tells a man named Noah to build a large ark. Noah brings his family and many animals onto the boat to stay safe. When the water goes away, a rainbow appears as a sign of a promise. 
These stories appear in many different parts of the world. In Greece, the god Zeus sends a flood to punish humans. A man named Deucalion builds an ark to escape the water. In Hinduism, a man named Manu is warned by a god to build a giant boat. North American tribes also have these traditions. The Blackfeet people tell of a deity named Napi who used colored water on a mountain. The Hopi people have legends of floods that reached the tops of mountains. These stories show how many cultures thought about great changes in the world.
Some people look for real reasons why these myths exist. Scientists know that sea levels rose a lot after the last ice age. 
Other people wonder if seeing fossils helped create these ideas. Ancient people found seashells and fish bones high up on mountains. This might have made them think the land was once under deep water. In Greece, people used these fossils to support their own stories. Some also look at the story of Atlantis as a possible memory of a lost society. Whether from real floods or old observations, these stories help us understand how people viewed the world. They turn big, scary events into stories that people can share and remember.
A flood myth, or deluge myth, is a narrative describing a massive flood that destroys human civilization. These stories often suggest the water is sent by one or more deities. This destruction is frequently described as an act of divine retribution. Some traditions view the floodwaters as a way to cleanse or purify humanity of corruption. This process prepares the world for a rebirth or a new beginning. 
In Mesopotamian traditions, the flood is linked to the relationship between gods and humans. In the Sumerian and Akkadian traditions, gods once transformed the steppe into a fertile garden. This introduced agriculture to the Earth during the Neolithic Revolution. However, the hard labor required for this caused a revolt among the lower gods. Humans were eventually created in pairs to perform this work for the deities. Eventually, the noise of the growing human population disturbed the upper gods. The god Enlil decided to unleash a mighty flood to wipe out humanity. To save humanity, the god Enki secretly warned the priest Atrahasis. Enki provided detailed instructions for building a boat, allowing the family to survive.
Similar themes appear in the Hebrew Bible's Genesis narrative. In this account, the god Yahweh decides to flood the Earth because mankind has become corrupted. Yahweh instructs a man named Noah to build an ark. Noah brings his family and representatives of all animals onto the vessel. After the waters recede, Yahweh promises never to judge the Earth with a flood again. He uses a rainbow as a sign of this sacred promise. This story shares the motif of a single family surviving to preserve life.
Different cultures across the globe hold their own unique flood traditions. In Hinduism, the Satapatha Brahmana and the Puranas describe a flood called manvantara-sandhya. The Matsya avatar of Vishnu warns the first man, Manu, to build a giant boat. In Greek mythology, the Titan Prometheus tells his son Deucalion to build an ark. This advice helps Deucalion escape a flood sent by Zeus to punish the Bronze race of humans. Zoroastrianism also contains a flood story involving an ark and cattle. In North America, the Blackfeet people tell of the deity Napi. Napi gathered people on a mountain and used colored water to influence their languages. 
Scholars have investigated whether these myths are based on historical events. One theory suggests that floods following the Last Glacial Period inspired these stories. This period occurred between 115,000 and 11,700 years ago. Another possibility involves an oceanic asteroid impact. Archaeologist Bruce Masse analyzed 175 myths to find connections to such an event. He suggests a meteor or comet may have hit the Indian Ocean between 3000 and 2800 BCE. This impact could have created the Burckle Crater and a massive tsunami. 
Geological evidence also provides clues about ancient flooding. In Mesopotamia, the region was often prone to flooding. Excavations at Shuruppak revealed a 60-cm layer of sand and clay. This layer dates to around 2900 BCE and indicates a major flood event. This may have been caused by river avulsion, where a river changes its course. Additionally, global sea levels rose significantly after the last glacial maximum. Sea levels rose from 18,000 BP until they reached current levels around 8,000 BP. This change would have altered the geography of many coastal regions.
Finally, some researchers look to human observations of the natural world. Historian Adrienne Mayor suggests that seeing seashells and fish fossils in mountains may have inspired these stories. Ancient Greeks, Egyptians, and Romans all documented finding these remains in inland areas. The Greeks believed this was evidence that the Earth had been covered by water before. In the Mediterranean, some speculate the Deucalion myth relates to the Thera eruption. This eruption occurred approximately between 1630 and 1600 BCE and caused a large tsunami. These various connections show how myths relate to geography, geology, and history.
