Are Genesis 1-2 really two distinct stories from two different sources? Or might they be one unified text that is more like an ancient puzzle than a traditional linear story?
In the Talmud is a discussion among Rabbi Eliezer, Rabbi Joshua, and Rabbi Akiva about the day when Adam was created. One said he was created on the first day, another the second day, and Rabbi Akiva said the Adam was created on the sixth day. Rabbi Elazar also spoke of the light that was created on the first day, which was seen from one end of the world to the other by Adam.
These great Sages could only posit the creation of man on the first or second day if they were using a different arrangement for the order of the verses of Genesis 1-2.
The traditional version of Genesis 1-2 is arranged according to an alphanumerical order. To read it properly you need to fold the Biblical Gematria cipher into halves. All the verses until 2:3 described aspects of creation that were made by God during the seven evenings. All the rest of chapter 2 described aspects of creation that were set in motion during the seven mornings. The task of this ancient puzzle is to match each morning with each evening to narrate a complete day, and this is why each day ends with the phrase “and there was an evening and a morning”.
