Depends on whose YouTube videos you watch.
Let's talk about a hard colonization where it's literally- They're everywhere.
It's transforming the freaking planet into machines.
That clearly has not happened here.
We're not gray goo on the surface.
So we know that hasn't happened.
And we also know, and the universe, the galaxy's old.
It's 13 billion years old.
So there's a heck of a lot of time for that to happen.
One of the strangest facets of our technology is that it's already fast enough to explore the whole galaxy.
If you take Voyager 2, it was traveling at 15 kilometers per second.
So that would get you across the entire diameter of the galaxy in 2 billion years.
And the galaxy is 13 billion years.
So Voyager 2, at Voyager 2 speeds, crappy alien technology out there could already have spanned the whole thing if they just arrived early enough.
