How did God make all the people?

Every person on earth came from Adam and Eve.  God made Adam out of the dirt of the ground and breathed into him the breath of life, making him a living soul (Genesis 2:7).  God made Eve by taking a rib from Adam and forming her that way (Genesis 2:21-22).  After some time mankind did only evil and God decided to flood the earth (Genesis 6:6-7).  God spared Noah and his family and it is through the sons of Noah that different people groups were formed.  After the Tower of Babel these groups spread across the whole earth, creating the different cultures and traditions we see today.
