But we should think of alien civilizations that could have existed for millions or billions of years before us,
And I think it's much more natural to expect that things better than us existed for billions of years,
Most of the civilizations that predated us by billions of years may not be around anymore.
And so just arguing that something like us existed billions of years ago, you know, is an ordinary claim.
It's not extraordinary. And I say billions of years ago because most stars from billions of years before the sun, the sun formed only in the last one third of cosmic history.
And so billions of years are passing in the rest of the universe, in your accelerating frame, which is just accelerating at 1G, you know, it's nothing.
If they have a fast enough technology, if they are using chemical proportions, rockets like we use, they would get here within millions of years, which is again a very short time compared to the billions of years that characterize the...
