We might be lucky enough to do that, but it could have easily taken intelligence another 500M years to evolve on another planet. First animal fossils are something like 700M years old, so it took 2-3G years to just any animals.

The problem is that there are just so many planets. Sure, another planet could be 500My slower, but with a billion planets, some of them should be 500My faster instead.
It's possible we are absolutely one-in-a-billion uniquely lucky - after all, someone has to be the first and the luckiest. But every year we find indications that our planet is completely typical.
