I am an old guy. The older I get the smarter I seem to get (relatively speaking). It is my opinion that we are NOT alone in the universe and that ET's have been visiting us for some time. the internet has a plethora of info on this fascinating subject. I worked for Uncle Sam for 30 years and would not be in the least surprised if he has been covering up info on this subject. Anyway it is an awesome tool we have here with the internet. The amount of information out there is truly astounding. the use of a search engine gives us information that no human has ever had, at the touch of a button. I just wish that I would have had the privalege to use internet when i was a kid in school.
Thanks for all the help out there in cyberspace you fine people of earth,........
