I think it is highly likely that human beings are not only one of many intelligent species, but we are at the bottom of the totem pole when it comes to developing civilizations.
It is highly likely, in my mind, that human beings are being prepared for contact within the next few months/years. We are being tested to see if we qualify living here one Earth, and also whether or not we can reach a voice of unity which will take a seat on some form of Galactic Federation, who are patiently awaiting (and even guiding) our initiation towards space migration and life extension.
