Humanity (Scriptures)

According to the accounts in the Book of Genesis, humanity was described as being very wicked and vicious before the Great Flood during Noah's days. The people were discussed as being very evil to the point that God sent a global flood to kill every living thing on Earth, besides Noah and his family.

Description
The people who lived on the Earth prior to the Flood were described as doing many unspeakable actions such as murders, rapings, and many other heinous actions. Some of the earthly women have also have become involved with angels of God and intermarried and raised the cannibalistic race The Nephilims. Their wickedness was so great that God regretted ever creating humanity. He set his eyes on Noah and found favor with him. He then tells him to build an ark large enough for his family  and two of every animal of the world so that they could have refuge during the forty days and nights of the Flood.

In the meantime, Noah took this opportunity to try to convince his neighbors to change their ways, lest they would suffer the wrath of God. However, they made fun of him stating that there was no rain before and that he was insane. When the rain started to come down, Noah's neighbors realized that Noah was right about the Flood, and sought refuge from the ark. However, it was too late, as God had shut the door on them, and they drowned. The floodwaters slowly but surely spread throughout the world, purging its wickedness.

After this genocide, God swore to never flood the world again, and set a rainbow in the sky as a sign of this promise.
