The Beginnings of Mankind
Adam HaRishon was the first man. Hashem created him from the earth of the ground, and thus he was called Adam, meaning “earth.” Hashem created a wife for Adam. Adam called his wife Chavah because she was the mother of all people. 
Hashem planted a garden in Eden, to the east, and placed Adam and Chavah there. Hashem told them, “Of every tree of the garden you may eat, but from the Tree of Knowledge of good and bad you may not eat.” 
However, Adam and Chavah ate from the Tree of Knowledge, and Hashem banished them from Gan Eden. Henceforth, Chavah would have to endure pain at childbirth, and Adam would have to find his sustenance only through hard work.
Chavah conceived and bore a son and named him Kayin. She bore a second son named Hevel. Hevel became a shepherd and Kayin a tiller of the ground. 
Both Kayin and Hevel brought offerings to Hashem, but Hashem
accepted only Hevel’s offering. In jealousy, Kayin killed Hevel. Hashem cursed Kayin and decreed for him a life of wandering.
Adam knew his wife again, and she bore a son called Shes.
The Ten Generations from Adam to Noach
The world was populated by the descendants of Adam and Chavah. After ten generations, in the year 1056, Noach was born.  He was descended from Adam and Chavah through Shes and lived for 950 years. Noach had three sons: Shem, Cham, and Yafes. ln Noach’s generation, the world was corrupt and evil. People practiced idolatry, and theft was common. Only Noach remained righteous, as it says: “Noach was faultless in his generation; Noach walked with G-d .” 
Hashem told Noach that he must build an ark, a teivah, for He
intended to bring a flood that would destroy all life on the earth. 
Hashem told Noach to bring to the ark one pair of all non-kosher creatures, a male and a female, and seven pairs of all kosher creatures, so that life could be replenished after the Flood.
In the year 1656 after Creation, the Flood came and destroyed all
life. The fountains of the deep opened up, and from the heavens the rain fell for forty days and forty nights. Only after a full year was the earth habitable again. The ark came to rest on the mountains of Ararat, and only those in the ark survived—Noach, his family, and the animals. After the Flood, the world was repopulated through the sons of Noach.
Mankind had been given six laws as the basis for life. After the
Flood, Noach was given another mitzvah, since, for the first time, man was permitted to eat meat. This additional mitzvah was: “Do not tear a limb from a living animal.” 
These seven mitzvos are known as the sheva mitzvos b’nei Noach
(Seven Mitzvos of the Children of Noach), and all of mankind is required to live according to them.

 The name הוה (Chavah) is from the same root as the word חיה (chayah), which means “living” (Bereishis 3:20 Rashi). Thus, the name Chavah indicates that she was the mother of all people.
