It's great to search for green planets, but the answer to are we alone has been answered publicly more than 40 years ago.  They are not that different.  They are human.  And they have been coming here for hundreds of thousands of years.   The information is in the Billy Meier contact reports.  More than 8000 pages and more than 2000 pieces of evidence.  All questions have been answered.  So I don't care what university you work for or how man degrees you have.  Scientists are stupid if they haven't found this information. I mean, completely useless when it comes to these questions that have already been answered years and decades ago.
