Or by the time their response arrives we'll have gone extinct a long time ago.Outright Villainy said:More likely:Homo sapiens have only been around for roughly 200,000 years, and haven't been doing very much for most of that time. In fact, only within the last century have we advanced technologically to the point of contacting said Aliens with radio waves.siddif said:also believing that there are no aliens out in space because they havent come to us is also very vain - maybe we are the least advanced creatures in the universe and they take pity on us or treat us like intergalactic pets
Now, the main thing here is that space is monstrously fucking huge. What you're asking is for there to be a hugely advanced civilisation, capable of interstellar travel, who would take off at the mere sight of human evolution. Except with light (and any subsequent information) taking so long to get there, it could take millions of years for that information to travel far enough for such a civilisation to see it.
And lets say they do. They see some monkeys standing upright drawing shit on walls.
Are they going to up and leave their planet, and travel untold vast distances, you know, for the hell of it? What would they possibly gain? What could they do instead? Send radio waves.
We've already done that. They haven't gotten very far yet.
I'm assuming that untold millions of years from now we'll pick up a return radio wave that says "hi" in their language.
And we won't know what to fucking make of it.
Edit: removed spoiler tags because it fucks with the formatting.
Or they're extinct before our message arrives...
