Hello
@LayHong_Loves_Christ, the Bible tells us that people were dwelling in tents, and that fire was being used to forge tools of bronze and iron just seven generations from Adam/Eve. Surely the use of fire for cooking and to stay warm happened much earlier than that however. In fact, because the "
fat portions" are mentioned as part of Able's sacrifice to God, I believe that fire was already in use for various purposes all the way back then .. cf
Leviticus 3:12-16.
Genesis 4
1 The man had relations with his wife Eve, and she conceived and gave birth to Cain, and she said, “I have gotten a manchild with the help of the LORD.”
2 Again, she gave birth to his brother Abel. And Abel was a keeper of flocks, but Cain was a tiller of the ground.
3 So it came about in the course of time that Cain brought an offering to the LORD of the fruit of the ground.
4 Abel, on his part also brought of the firstlings of his flock and of their fat portions. And the LORD had regard for Abel and for his offering.
16 Then Cain went out from the presence of the LORD, and settled in the land of Nod, east of Eden.
17 Cain had relations with his wife and she conceived, and gave birth to Enoch; and he built a city, and called the name of the city Enoch, after the name of his son.
18 Now to Enoch was born Irad, and Irad became the father of Mehujael, and Mehujael became the father of Methushael, and Methushael became the father of Lamech.
19 Lamech took to himself two wives: the name of the one was Adah, and the name of the other, Zillah.
20 Adah gave birth to Jabal; he was the father of those who ~dwell in tents~ and have livestock.
21 His brother’s name was Jubal; he was the father of all those who play the lyre and pipe.
22 As for Zillah, she also gave birth to Tubal-cain, ~the forger~ of all implements of bronze and iron; and the sister of Tubal-cain was Naamah.
