Did God create other people in addition to Adam and Eve?The Bible nowhere indicates that God created other people in addition to Adam and Eve. All other human begins were created through normal reproductive processes, with the exception of Jesus. In Genesis 2 we read that God created Adam from the dust of the ground; He created Eve from Adam's rib. The New Testament also refers to Adam as the first human from whom all others descend (Romans 5:12–14; 1 Corinthians 15:22, 45–49; 1 Timothy 2:13).
Genesis 2:7 says, "Then the LORD God formed the man of dust from the ground and breathed into his nostrils the breath of life, and the man became a living creature." God made "the man" and "the man" was alive. There was just one man—Adam.
Then, God used what He had made in Adam to create Eve. "So the LORD God caused a deep sleep to fall upon the man, and while he slept took one of his ribs and closed up its place with flesh. And the rib that the LORD God had taken from the man he made into a woman and brought her to the man" (Genesis 2:21–22). Again, see that the female person God created here is singular—"a woman."
There is no account or indication anywhere else in the Bible that God created any other people. Everyone else in history has descended from Adam and Eve. This causes some questions to arise, such as "After Cain killed Abel, who did he have to fear?" (Genesis 4:14). We know that Adam and Eve had more children than Cain and Abel (Genesis 5:4). Cain must have feared his other siblings, nephews, nieces, and other relatives, all descended from Adam and Eve, who might seek revenge. Another common question is "Where did Cain's wife come from? Who was she?". In a pre-flood world there would be no issue with Cain marrying a close relative, so his wife must have been a sister or niece.
Another question that arises is "If Adam and Eve were of one specific race, where did the other races on earth come from?" First, keep in mind that there is only one human race. However, it is true that there are a variety of different skin tones and other physical features that are common to people of a certain geographic location or ethnicity. Likely, God created Adam and Eve with the genetic potential to produce children with a variety of skin tones and other physical features. When God preserved the lives of Noah and his family (Genesis 6—9), the different members of that family may have had variant physical features or retained a wide spectrum of genetic possibilities. Additionally, when God imposed different languages on the people of Babel (Genesis 11:1–9) and they scattered, people of similar languages would have probably lived in relative isolation from the others. As similar people began reproducing with one another, their similar traits would have reproduced and become more exaggerated and then characteristic of that region. We really do not know, but there are plausible theories that easily account for all the "races" descending from the first two humans.
What we do know is that God created the entire universe and He formed Adam and Eve as the first humans from whom all others would descend. God has made all human beings in His image (Genesis 1:27) and with the desire that each person is to be in relationship with Him for His glory.
