We still need to leave a heck of a collection. On a living, evolving planet if all civilizations are gone the signs get wiped out pretty fast in geological time (geology, weather), and in space the signs are usually traveling in the emptiness with little chances of being spotted. The best probes will eventually fail and will just add to the countless objects floating never to encounter anything.

I know it sounds depressing but I keep getting reminded of this [0] when thinking of loneliness in the universe. It's the most apt description I came across in recent memory.

On the other hand, large objects made by us on the Moon could last for 100's of millions of years. Especially if the object was designed to last that long.

I like the comic.

It's almost like all intelligent life in the universe was put into escape-proof cages.

We need to rage against this! Do it for all the others who can't.
