It should not be surprising that Evangelical Creationists and fundamentalists of all religions are much less likely to believe that alien life forms exist anywhere else in the Universe. For Evangelicals, such 'geocentrism' centers on the Original Sin.
"Do extraterrestrial aliens have original sin? I don’t know if there are such beings. I have difficulties with the notion of original sin. However, if such beings do exist, and if they are subject to death and are capable of evil, they will need some sort of redemption."
