I think we nuke the whole planet from orbit; it's the only way to be sure.
But seriously? I believe that it is almost certain that life exists out there. I also believe that it is almost certain that said life has not visited us. Think about the logistics: If an alien culture discovered Earth, the Earth they would see would be far in the past, most likely far enough that it wouldn't be worth investigating, as it would be a steaming ball of rock and clouds. Even if they did decide to check us out, barring FTL travel, it would take a LONG time. Long enough that they couldn't be sure that the conditions of our planet would be the same, or if our planet still even existed. And if they did make it all the way here, the chances of that alien culture developing to that point to reach here at the point of recorded history makes the probability infinitely small.
