no we are not alone, have never been and never will.
we have been told a lie about our history on earth and things been hidden from us, any if some one is wondering why they dont conntact , they already have, but what would you do if the ET would stand in front of you , shoot first ask qestion s later or communicate in peace.

I would choose the second one , and dont forget that we are for other s ETs an Alien spieces living on earth in the Milkyway Galaxy.

all the best Skarpi
