I agree with you, provided that such a civilization could last millions of years. Our civilization acquired the means to extinguish itself about 60 years ago and we almost did it.my_wan said:Funny ghost got more votes than bigfoot :surprised
If even 1 spacefaring race managed to colonize mutiliple worlds it would not only greatly improve long term chances of survival but withing a few million years they would essentially own at least the galaxy, even with the present limitations in physics as we know them. Such a race would likely posses godlike powers in our estimation. What are the odds this hasn't already happened? However unlikely it's certainly not 0. Such a race would be unlikely to depend on a planet for providing life support, only raw materials.
Point is that even though by far the greatest probability is that we are essentially alone at least in this galaxy the possibilities are more outrageous than we can possibly imagine. We suffer culture shock just moving around within our own societies and we want to pretend we can intellectualize races millions of years more advanced. It's fun to try though
Will we be able to leave the planet before we deplete it from all its resources through exploitation and pollution? I don't really know.
Provided that another race has escaped self destruction and is going where no LGM has been before, would they need to mutilate cattle, draw crop circles and introduce anal probes in human beings? I don't think so! As you said, such a race would be godlike in our eyes and could study the life in our tiny rock with less invasive means.
Besides, escaping self destruction means that they achieved not only advanced technology, but advanced moral principles, so they would not kill and torture living beings, specially sentient ones.
