A fascinating topic. I had missed the previous posts.
Like life after death,this is probably one of the most brain-twisting issues bugging humanity for centuries.
I stopped speculating about it.
My best guess is that for extraterrestrials we must be some kind of plague you'd better stay away from.
If there are living forms more advanced than us, they must be intelligent enough to understand that not much good may come from interacting with us, unless you decide to get rid of probably 90% of the population.
The immensity of the universe is mind-blowing enough. I think we will destroy ourselves before we can find life somewhere else.
