I have read in the Yalkut Biurim-section of the Mesivta Gemara Sanhedrin (p. 98 of the Yalkut Biurim), that the six days of creation are intertwined with the teaching that the world will exist for 6000 years (Sanhedrin 97a and Avodah Zarah 9a). This explanation seems to be based on the comments of the Ramban (Thanks Rabbi Kaii!).
The Yalkut Biurim brings that the third day corresponds to the generation of Avraham Avinu. Avraham Avinu was like the flowers and the trees that sprouted from the earth, that is to mean that he did bring Torah into the nations and learned them about G-d.
However, the other days are described as follow:
- First day: G-d seperated light and darkness
- Second day: G-d created the firmanent that separated the waters
The Yalkut Biurim says the second day corresponds to the generation of Noach, in which, by means of the flood, good was separated from evil. But, wouldn't it be more logical to say that this happened when G-d separated light from darkness?
Are there any commentaries, meforshim, seforim that explain this list the Yalkut Biurim brings, in which the days of creation corresponds to the generations in which we live and why this specifical order is used, or is this an chiddush on itself?
