Adam was the first man and Eve was the first woman. Genesis 1 gives the summary of creation, while Genesis 2 gives some extra detail, including the information that God had created a male first (Adam) and only created a woman (Eve) after the man had realised that none of the animals was a fit helper for him.
The minor complication here is that ‘adam’ in Hebrew can be a name or can simply mean ‘the man’. See What does “man” mean in Genesis? for more information. However, the narrative in Genesis 2-4 makes it clear that there was only one man and one woman at this time. Later in the Bible, this is confirmed by the descriptions of the man Adam (Luke 3:38; Romans 5:14; 1 Corinthians 15:22, 45; 1 Timothy 2:13-14) and how Eve was deceived (2 Corinthians 11:3; 1 Timothy 2:13-14).
For an alternative view, see Did God create other people besides Adam and Eve?.
Some people teach that a race of people made iin Genesis 1 were like a pre – adamic race. They supposedly were the cavemen in the evolutionary line. Therefore God used evolution to create the world. One of the big problems with this teaching though is Romans 5:12. It says, “Therefore just as through one man sin entered into the world and death through sin, and so death spread to all men, becasue all sinned.” This verse helps us to see that before Adam sin and death werent here, but after Adam sinned, sin and death came. So that would mean that there would be countless years of death and disease, before Adam. This just simply cannot be true. Please pray for discernment and the Lord will give it to you.
Just because “through one man sin entered into the world
and death through sin, and so death spread to all men, because all
sinned”, does not prove that Adam was the first “being” on earth.
“so death spread to all men”, what other men? What about in Genesis
3:22, And the LORD God said, Behold, the man is become as one of
us, to know good and evil: and now, lest he put forth his hand, and
take also of the tree of life, and eat, and live for ever: he is
talking to his first earth age creation. How else can you explain
all the races?
In 1 Corinthians 15:45 Paul states that Adam was the first man. Genesis 3:20 shows that Eve was the mother of all people. Regarding who God is speaking to in Genesis 3:22, see the answer to a very similar question: Who is God speaking to in Genesis 1:26?. An answer to the question of races is given in How do we get all nationalities like Native Americans from Adam and Eve?
i read the beginning of the creation and it all suggest that there were other man on earth beside Adam and Eve. If there were only adam eve and cain who does caien afraid off? his sibling? how many sibling would have been alive at that time? how often does eve giving birth? I know we will never know exactly the answer to these question. we can only speculate. In fact a second reading suggest that there were no other siblings at the time cain killed abel. read carefully genesis 4. genesis 5:1 clarify more about the cration of mankind. genesis 6:2 the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose. really make it clear that there were sons of God who are other God creature and human who are adam and eve other children… I dont think it could have been clearer …
