Meanwhile, the being from 'out there' might think: "Jeez, that's what our four year old does. We're moving on."
I think the problem here is too many people are thinking on
very short timeframes. Look at how much our society has changed just in the last 200 years. It's not like everything is operating on the same time table as we are. Any civilization out there is going to be on some random point on the continuum of evolution. The odds of them being in the same ballpark as us is incredibly slim.
It's much more likely they're ether painting caves or reorganizing planetary orbits etc, not doing any activity that even remotely resembles our current society. So either they're ants to us, or we're ants to them. Babylon 5 was the only sci fi series that I can recall that had any similar take on this. G'Kar was discussing The First Ones:
Catherine Sakai: Ambassador! While I was out there, I saw something. What was it?
G'Kar: [points to a flower with a bug crawling on it] What is this?
Catherine Sakai: An ant.
G'Kar: Ant.
Catherine Sakai: So much gets shipped up from Earth on commercial transports it's hard to keep them out.
G'Kar: Yeah, I have just picked it up on the tip of my glove. If I put it down again, and it asks another ant, "what was that?" [laughs] How would it explain? There are things in the universe billions of years older than either of our races. They're vast, timeless, and if they're aware of us at all, it is as little more than ants, and we have as much chance of communicating with them as an ant has with us. We know, we've tried, and we've learned that we can either stay out from underfoot or be stepped on.
Catherine Sakai: That's it? That's all you know?
G'Kar: Yes, they are a mystery. And I am both terrified and reassured to know that there are still wonders in the universe, that we have not yet explained everything. Whatever they are, Miss Sakai, they walk near Sigma 957, and they must walk there alone.
That's pretty fundamental wisdom in this area. Don't think "our four year old", think
ant. Anything more is really extreme arrogance. To think that we must be clever enough to understand them is just as arrogant.
Go to youtube and search for "the great filter". You won't find anything on it on Wikipedia, which I find very odd. But there's plenty of discussions on youtube. It's an attempt to answer the Fermi Paradox.
