Is There Life on Other Planets?

by Greg Reeves

If you’ve been reading the science news lately, you’ll find there has been a lot of buzz about “extrasolar planets”, or “exoplanets” (i.e., planets that orbit other stars).  For an example, see here.  The reason why is in the last several years, the number of exoplanets that we’ve discovered has increased dramatically, mostly due to the Kepler mission.  But regardless of the reason why, one interesting question this brings up is, “Are there other planets that host life?”

This is an incredibly profound question for both the religious and non-religious alike.  For the Christian, the knee-jerk reaction might be “no, of course not, God specially created the life on earth and did not do so elsewhere.” (By the way, I do not necessarily espouse this view.) For the secularist, the presence of life on other planets only adds weight to the idea that life arose here on earth by strictly naturalistic processes.  So what does science have to say about this subject?  Given the sensationalistic popular news articles, one might think the universe is teeming with alien life.  However, the data actually say otherwise.

First, answering the origin of life question, from a scientific standpoint, is incredibly hard.  In fact, after investigating the state of affairs on this problem in order to write a book, it has driven agnostic physicist Paul Davies to proclaim1:

When I set out to write this book, I was convinced that science was close to wrapping up the mystery of life’s origin…Having spend a year or two researching the field, I am now of the opinion that there remains a huge gulf in our understanding…This gulf’s not merely ignorance about certain technical details, it is a major conceptual lacuna.

He goes on to say:

Many investigators feel uneasy about stating in public that the origin of life is a mystery, even though behind closed doors they freely admit that they are baffled. There are two reasons for their unease. First they feel it opens the door to religious fundamentalists…Second, they worry that a frank admission of ignorance will undermine funding…

Second, even though it is a conceptually difficult phenomenon to study, scientists are incredibly confident that it will be resolved one day.  The main reason why is that the alternative to having a naturalistic origin of life would be a supernaturalistic origin of life, something that most secular scientists not only do not believe in but also that they rule out completely according to their philosophical worldview…
