Well as I see it, after all these years of comms radiating out to the multiverse, they probably already know we're here.
It is pretty reasonable to say that if they are more advanced they will come to us before we get to them...but what does advanced mean?
More compassion, like humans are showing the planet and it's inhabitants? As a species we argue about everything and time and time again arguments
lead to escalation. One of our biggest faults is belief, belief we are right, belief in belief, belief in what we do not know!!
Yes ET, if he is out there may be violently disposed towards us. I think if I visited a world where the dominant species was destroying it, I would
feel the need to do something...maybe he would too.
But really I don't think it relevant. If they are already on the way, there is nothing we can do....except like the jews at Masada, deny them victory
I suppose....but maybe we are on the way to this with our treatment of the Earth already
So as I see it we can't do 'owt about it and the very possible threats of global-warming and meteor strike will probably affect us before we succumb
to a master race...and if we're honest...we can't do much about them either....
So as Frasier from "Dads Army" says "We're doomed!!".
I feel a kind of peace knowing we won't be round much longer....
