Genesis chapters 1&2 are probably the most misunderstood topics in the Bible. The Hebrew words translated into English are similar but not exact. The only way to know the exact meaning of the Hebrew words is to have a copy of “The Complete Word Study Old Testament”.
This is good Bible study and has been part of Pentecostal teaching for
nigh on a hundred years.
there were two creations - chapter 1 are all the major races of the world
who would have started off as hunters and gathers
chapter 2 - where Adam was formed and Eve was formed from Adam
some 40,000 years later than chapter 1 on the 8th day
and he was separated from the rest of humanity and placed in a garden
Adam and Eve specifically represent the first church, the beginning of the
plan to bring salvation into the world through a chosen one to come
the first Adam and the second Adam.
We know that other people existed in the world when Cain complained
to God about the mark placed on him
13 And Cain said unto the LORD, My punishment is greater than I can bear.
14 Behold, thou has driven me out this day from the face of the earth;
and from thy face shall I be hid; and I shall be a fugitive and a vagabond
in the earth; and it shall come to pass, that every one that finds me shall
slay me.
Genesis 4:
We also know that other people inhabited the earth apart from Adam's family
16 And Cain went out from the presence of the LORD, and dwelt in the land
of Nod, on the east of Eden.
17 And Cain knew his wife; and she conceived, and bare Enoch: and he built a city,
and called the name of the city, after the name of his son, Enoch.
