That's sad and beautiful .
I only wonder why humans still think that it's the possibility of being found which is a major determining factor.
Any intelligent life out there would look at the junk pile from our planet floating around in our atmosphere made of old rockets and whatever and be
disgusted by it.
As far as this being a "message in a bottle" I say ; good luck.
It's going to be perceived as something nasty that came floating out of that stinky and ridiculous planet called earth; stinky and nasty because its
people don't take care of it.
They will then ZOOM in on the junk pile that floats in the Pacific Ocean and be like; so... why would we want to go there?
Message in a bottle.
This will look like a piece of s$#t floating out from our planet to anyone watching it
