How can we say : Hey you mr. alien guy you, I and the whole world would like you to come and have a cup of tea, If we "ALL" dont "Know" for sure they even exist in the first place ? Well i think it is possible that they may have to "show" the whole world that they do exist for sure for us to even want them to come and have a cup of tea , no ? So as far as free will goes , they first need to show up and give us the option of having the dicision to make a "Free will " choice right ? So in my humbble opinion i beleave it "could" happen indeed ! But like he said , many people say many things that never happen ! So when it is all said and done, the only thing for us to do is wait.
