Luis Elizondo, personal beliefs and UFOs.

“My personal belief is that there is very compelling evidence that we may not be alone.” Those are the words of Luis Elizondo, who ran the Advanced Aerospace Threat Identification Program from 2007 to 2012 for the Pentagon. This was said on CNN during an interview with Erin Burnett, you can watch the interview below.

Notice in the interview a video is shown of one of these aerial anomalies encountered by a Navy Pilot. While Elizondo makes much of this video others are not so convinced. Dr Francisco Diego of UCL's Science and Astronomy Department thinks the video is probably fake or some sort of optical illusion.  

At the end of the day I think what Elizondo presents is his “personal belief” that there is “compelling evidence” for the existence of extraterrestrial life. This is still a personal belief; some may find personal beliefs persuasive but as far as critical thinking goes they don’t pack much of a punch. Furthermore, we have not been presented with any “compelling evidence” as the video with the Navy Pilot hardly fits the bill of “compelling.”

Most importantly I think such claims need to be appraised by how well they cohere with already established scientific facts. One of such facts is the Fine tuning of planets for life. Scientists once theorized that life elsewhere could be made up of other chemicals and need not be carbon based as life on earth. But this has been refuted, physicist Robert Dicke has deduced long ago that if there are to be life forms anywhere else in the universe they have to be carbon-based. [1] Consequently, scientists have been able to come up with a list of conditions that specify if a planet is capable of supporting life. 
Astrophysicist Hugh Ross lists 153 of these known parameters or conditions and concludes that “the probability of a planet anywhere in the universe fitting within all 153 parameters is approximately 10-194. The maximum possible number of planets in the universe is estimated to be 1022. Thus, less than 1 chance in 10172 (100 thousand trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion) exists that even one such planet would occur anywhere in the universe.”

Since the odds are stacked heavily against there being a planet that could support carbon based life forms apart from earth, the most obvious question to ask when UFO talk comes up is where do these UFOs come from? That is a question for Luis Elizondo to answer.
