Babylon 5, Season 1: Signs and Portents

Catherine Sakai:
While I was out there, I saw something. What was it?

G'Kar:
[pointing to a nearby flower] What is this? [upon closer inspection, an insect is visible]

Catherine:
An ant.

G'Kar:
"Ant"!

Catherine:
So much gets shipped up from Earth on commercial transports, it's hard to keep them out.

[As Catherine is talking, G'Kar carefully picks up the ant.]

G'Kar:
I have just picked it up on the tip of my glove. If I put it down again [replacing the ant on the flower] and it asks another ant, "What was that?" …how would it explain? There are things in the universe billions of years older than either of our races. They are vast, timeless. And if they are 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 we can either stay out from underfoot, or be stepped on.

Catherine:
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, Ms. Sakai, they walk near Sigma 957. They must walk there alone.
