It is worth recalling that the reason the Torah spends so much space on the details of this list of the descendants of Cham is to inform us about how many nations were descended from him is to make us aware that Avraham, a descendant of Shem, merited to become the father of the Jewish nation. The Torah hints that the only reason that there was a need for seventy nations in the first place was to ensure that out of all these there would emerge at least the one nation that G’d has chosen to become special to Him.
Our sages (Tanchuma Vayeshev 1) have illustrated the matter by means of a parable. When someone loses a pearl on the beach, he will bring a sieve and sieve the entire sand on the beach in order to retrieve his pearl. Once he has found his pearl he throws the sand back on the beach. The parable intends to illustrate that just as all that sand on the beach only serves to yield up the one pearl, so there was no need for G’d to have all that many different nations except for that large number to eventually yield a Jewish nation. The sages said further (Bereshit Rabbah 1,8) that the concept of a Jewish nation had preceded the concept of all these other nations. We know that in G’d’s mind any end product had been carefully envisioned long before it would become manifest. This is also why the Jewish people did not appear on the stage of history until all the other nations already were in existence.
Normal intelligence dictates that any end product must have been planned before it was brought into existence so that of course it existed in concept long before it was actualized. It is possible to prove this from the construction of the Holy Tabernacle where the Torah specifically instructed Betzalel (Exodus 35,32) ולחשוב מחשבות, “to plan appropriate thoughts,” (for the construction of golden and silver furnishings for the Tabernacle).
