"Time" really doesn't happen in a linear way even though we think it does. Our brains can't handle it but our bodies do. We are such a makeup of our ancestors, all their strengths and weaknesses and feelings and habits. Global changes seem to come out of nowhere- maybe they come from the "future". The "past" continues to effect the present, for instance how styles and trends are repeated often based in the past. Even the past's science fiction and ideas of the future dictate how we modernize.
I really just think everything is happening all at once and consciousness could be so much more than it is. Maybe we just have to evolve to experience it.
