We can choose to do differently

So odds are our soot will still be here 66 million years from now,easy enough to find for any aliens who care to look.Of course, there's an important difference between us and an asteroid.A space rock has no choice but to follow gravity.We can choose to do differently.And if we do, there might still be some kind of human civilization thousands or even millions of years from now.Not a bad record to hope for.
