1:27 God created man in his own image. In God's image he created him; male and female he created them.

A Multidisciplinary Contextualized Analysis of Select Passages From Genesis V2.0

[This is an excerpt from an exhaustive personal study of most of the first 9 chapters of the book of Genesis. This is a vastly expanded effort from the original version that can currently be found here downloadable for free. The purpose of this exercise is to compare a non-symbolic literal reading of the text to our current understanding of language, paleontology, and the physical sciences. Constructive discussion on the merits of this study is encouraged!]

Approximate Year: 0.2 Ma (200,000 BC)

Historical Period: Upper Pleistocene Epoch

Event: Anatomically modern man

When read plainly, the singular form is used for “man” (hā·’ā·ḏām הָֽאָדָם֙). Arguably this may imply that at this point we are speaking of Adam and Eve. However, this would also be the case for the “tree” (“ets” עֵץ) in Genesis 1:11, “flying creature” (“oph” עוֹף ) in verse 20, and the “living creature” (“nephesh” נָ֫פֶשׁ) in verse 24. In all these cases only the singular is used, but it is meant to be a collective singular. Most translations appropriately pluralize most of these categories although there are also many use cases in English where the collective singular can be used in the same way.

Furthermore, the male and female are both “created” (Bara בָּרָא) in the same statement. No order of formation or hierarchy is implied between the sexes here as the phrase suggests a coincident origin. The semantics of the terminology is discussed in greater depth in the section on בָּרָא (bara), יָצַר (yatsar), בָּנָה (banah), but in brief this creation of mankind is a separate event than the later “formation” of Adam or subsequent “construction” of Eve.

Regarding lifestyle at this time, verse 29 implies that gathering fruit and nuts and domestication of animals were the norm for early humans. Archaeologists have discovered this was the case as the hunter gatherer lifestyle was universal until the end of the last ice age.

Homo Sapiens, which is considered to be "anatomically modern man", appeared roughly 200,000 years ago. It was sometime after that date this era would have reached its end.

1:31 God saw everything that he had made, and, behold, it was very good. There was evening and there was morning, a sixth day.
