Still the chances are so slim it would be virtually improbable. Don't mind the people who like to live for fantastical stories or be entertaining for their own sake.

"Three days into the Apollo 11 flight the astronauts on board sent a strange message to mission control asking, “Do you have any idea where the S-4B is with respect to us?” The astronauts were asking where the final stage of the rocket was, which had been detached two days prior. The reason for this inquiry was because something was riding along side of the rocket and if it wasn’t part of the rocket, Apollo 11 had a visitor.
The crew on board did not want to make a big deal out of the object for fear that it would cause a panic and mission control would order the astronauts to abandon the mission. “The three of us were not going to blurt out, ‘hey Houston we got something moving along side of us and we don’t know what it is’ we weren’t about to do that…someone might of demanded we turn back because of aliens or whatever it is,” said astronaut Buzz Aldrin when discussing the situation at a later date.
Mission control did answer the astronaut’s cryptic question about the location of the S-4b unit. The unit was 6,000 miles from their location. What Aldrin and the other three astronauts were looking at was an Unidentified Flying Object exhibiting an intelligent flight path. In fact, according to Dr. David Baker, an Apollo 11 Senior Scientist, astronauts seeing UFOs is not uncommon and dates back to the early earth orbit space flights.
If experienced and respected astronauts are seeing evidence of intelligent life outside of Earth it should also be taken very seriously."
Some people just don't want to believe, or won't until they see it first hand...while ignoring all the actual evidence. The word of a respected astronaut is damn credible.
As for your link..."Radio astronomer Frank Drake developed the Drake equation so he could estimate the number of planets harboring intelligent life in the galaxy by taking into consideration the factors listed above. A rigorous estimate using the Drake Equation was implemented in 2001, which also took into consideration the number of planets that are in the habitable zone (The habitable zone is an area around a star were water is in liquid form, temperature is ideal, and photosynthesis is possible).
The results found that hundreds of thousands of life-bearing planets statistically should exist. It also suggested that a habitable planet like the Earth should exist just a few hundred light years away."
