You've just reminded me of the similarities between the UFO debate and religious debate. Since you cant prove that something which doesn't exist 'doesn't exist', then we'll never prove that UFOs have not visited this planet.
It is possible that life exists on other planets, but its likely that we are in the first batch of life since life requires heavy elements and it takes life billions of years to develop which requires a star with a several billion year life span to develop after heavy elements were formed in earlier stars. That puts our main sequence sun at just the right mass and time scale to where we are among the first planets that is capable of supporting life in the universe. Add that to the fact that nothing can travel faster than light so if a more advanced alien civilization is out there colonizing then it will take them millions of years to get to us.
