58% Believe Life Exists On Other Planets

Americans continue to believe life exists in outer space, but they are less sure whether a human will walk on Mars within a quarter of a century.

A new Rasmussen Reports national telephone survey finds that 58% of American Adults think it’s at least somewhat likely life exists on other planets.  Thirty-four percent (34%) do not believe it’s likely.  That includes 33% who say it’s Very Likely life exists outside of Earth and eight percent (8%) who believe it’s Not At All Likely.

These findings mark little change from surveys dating back to early June 2007.

Forty-nine percent (49%) say it’s likely that a human will walk on Mars in the next 25 years, down slightly from December 2006. Forty-two percent (42%) think it’s unlikely a human will make it to Mars.  That includes 20% who say it’s Very Likely and eight percent (8%) who believe it’s Not At All Likely.
