So we cannot be sure..

Who is "we" ?

I already know nothing is sure. I was just adding new information.

You seem to have posted a question, as tentatively indicated by the question mark. So I was addressing that question.

The word "we" here refers to people considering the question that is being put forward - just as usually when this kind of phrase is used (e.g. "we will see", let us consider, and so on)
