And PS
I do believe we are all "tourists", interconnected more than we are different, and have borrowed a bunch of mass (body) to help communicate in this venue. And we'll have to give that mass back, "ashes to ashes, dust to dust" as they say.
But as for knowledgeable aliens, that's still a stretch.
And I apologize for the flip first post. Time for me to shut it down.
