Who was the first people to live on earth surface?

The first people on our planet were created by God.

“God made all sorts of wild animals, livestock, and small animals, each able to produce offspring of the same kind. And God saw that it was good. Then God said, “Let us make human beings in our image, to be like us. They will reign over the fish in the sea, the birds in the sky, the livestock, all the wild animals on the earth, and the small animals that scurry along the ground.”
So God created human beings in his own image. In the image of God he created them; male and female he created them.”
Genesis 1:26,27 NLTU

Genesis 3:20
"Then the man - Adam - named his wife Eve, because she would be the mother of all who live."
