It's scary to think it just us out here and I find it hard to believe that. There Is a theory that states possibly aliens know that we exist but we are yet to know how to understand their messages. Who knows.Hell what if they are waiting for us to mature before they contact usagain. Even the US military as seen some crazy shit and they of all people don't know. It's Cool to think there are others living deep in the galaxy but remember,there are over 1000 planets with earth like conditions. And if they want to abduct us, were clearly fucked or ready to take them on.
