No, what we are both talking about is considering the distances involved and the time-scale Earth would of already been colonised thousands of times over, millions of years before humans ever evolved, if that was even remotely possible. there are many many many planets that would of been hospitable about 10 billion years ago, at like 20-40 year by travel at speeds we have already mastered. We could send probes/colonization ships to them theoretically with the tech we have right now. Given all we know, they should already be about 6 billions years more advanced than we are, and they just apparently never colonised any planets, were never interested to see if their immediate neighbours had life on them, etc. And a single civilization just did not ever do any of these things, but hundreds or thousands of different unique ones. Billions if we go a little further out.
Considering the time-scale, and the distances, even a single seed planet on a single galaxy could of easily colonised every single planet on every galaxy.
Not having done so is like no animals, plants, insects or humans just ever making it over to the Americas. Just because, we just did not do it.
The only reasonable argument against this is that life on Earth has been evolving for around 9 billions years, and was seeded here by asteroids shortly after it became habitable. The idea being is that just now (give or take a few million year) advanced human like species are popping up all around the universe, and they all just started/will start soon/started not long ago exploring the galaxy.
