Who's "We"?

In class, we often have brought up the idea of "we" in terms of who specifically we're referring to in conversation. The first week of class, I believed that the sort of "we" we referred to was simply us as a class. The interactions we shared, the ideas we exchanged, etc. The more we've gone through class, however, my perception of the term "we" has slowly, but surely changed over time. From my understanding of the works of literature we've read thus far, the term "we" may as well be referring to those from different backgrounds and cultures. Much of what we've read (such as Mary Rowlandson's story and John Smith's account) show different cultures interacting with one another and, even if they don't agree on something, they are pretty much of the same people. How? They are all made by God and are therefore very much collective even if they don't understand each other. In other words, "we" refers to humanity as a whole.
