Terraforming Blooper?

In response to my previous post, some noted that if another planet of humans had terraformed our own Earth for their future use, millions of years ago, they made a big mistake because Earth got populated by people who evolved here before they could use it.

To that I say once again you make the mistake of assuming Earth is special. If we had the technology to terraform planets, and the predicted need, we wouldn’t take a chance on just one other planet. We’d spray a thousand probes into space all searching for their own planets to seed. Then when the time came, millions of years later, we’d colonize whichever one came out best, pushing aside any prehuman species that got in the way.

Therefore, if Earth was seeded for life by earlier humans, there is actually a very small chance they would choose Earth as one of the new planets they colonized. And that might be especially true if we evolved and populated the planet with humans before they had need for this planet.
