Are we alone ? Are the only living beings in the universe only found on Earth ?
Well from my limited knowledge of the vast scope of life and all the immense brain and computing power that mankind (womankind) has amassed...…..
So far the only facts we have to work with are...
1/ We haven't even fully explored 100% the depths and heights of this planet we live on.....
2/ We have seen and have knowledge of a massive array of lifeforms that have been catalogued are named and observed here on earth on land in the air and in water or combinations thereof...
3/ But there are still areas and lifeforms we haven't yet sussed out here on our doorstep...
4/ Only 12 humans have ever left earth and stood on another body in our universe that is not earth....
(Neil Armstrong, Buzz Aldrin, Pete Conrad, Alan Bean, Alan Shepard, Edgar Mitchell, David Scott, James Irwin, John Young, Charles Duke, Eugene Cernan, and Harrison Schmitt.)
5/ Out of all of those 12 who have stood on another body other than earth the longest stint was about 3 days on the lunar surface...
6/ So we haven't even been physically on another planet/moon/asteroid or anything other than earth for much more than a month in total...
7/ Our hands-on live experience of anywhere other than earth (which we still haven't fully explored) is pretty much insignificantly small compared to how much time we have had to explore Earth...
8/ We as a human race, man & woman... Still struggle big time predicting the weather on our planet, basic business and economic forecasts, understanding human nature or predicting fads and trends within our own population.... so it is quite probable that some assumptions and guesswork about what may or ,may not be out there beyond earth could be wrong.. or just wild guesswork!
THE SHORT SUMMARY IS:-
"WE KNOW BUGGER ALL ABOUT BUGGER ALL. IF ANYONE TELLS YOU DIFFERENT THEY ARE LIAR'S
