Your belief that Moses wrote Genesis has been outdated for many, many years.
Book of Genesis - Wikipedia
For much of the 20th century most scholars agreed that the five books of the
Pentateuch—Genesis,
Exodus,
Leviticus,
Numbers and
Deuteronomy—came from four sources, the
Yahwist, the
Elohist, the
Deuteronomist and the
Priestly source, each telling the same basic story, and joined together by various editors.
[16] Since the 1970s there has been a revolution leading scholars to view the Elohist source as no more than a variation on the Yahwist, and the Priestly source as a body of revisions and expansions to the Yahwist (or "non-Priestly") material. (The Deuteronomistic source does not appear in Genesis.)
[17]
Genesis is perhaps best seen as an example of a creation myth, a type of literature telling of the first appearance of humans, the stories of ancestors and heroes, and the origins of culture, cities and so forth.[20] The most notable examples are found in the work of Greek historians of the 6th century BC: their intention was to connect notable families of their own day to a distant and heroic past, and in doing so they did not distinguish between
myth,
legend, and facts.
Please be good enough to show writings from Secular scholars that Moses wrote Genesis. Also, please explain, with supporting documentation, how Moses knew what God did on the fifth day.
If you want to refer to your indoctrination as "Bible Training" that's your prerogative. I will gladly admit that I was not indoctrinated. Instead, I take my understanding of Genesis from a careful reading. I take my understanding of the origins of Genesis from scholars who know much more than either you or I.
