It is a commonplace of rabbinic commentary that Bereishit is the story of individuals - the avot - and Shemot is the story of a people.
Obviously, there is one outstanding personality in Sefer Shemot; however, while Bereishit can be fairly characterized as the history of individuals, it would not be correct to say that the central theme of Shemot is the life-story of Moshe. Nonetheless, as we examine the stories in Parshat Shemot, we see that there can be no question that the individual personality of Moshe is an important focus of the story of the exodus, as it is a crucial link in the development of the people of Israel.
