I don't know what was meant by "scientologist" (maybe someone who studies science? But there is no good word for that ever since epistemology changed meaning). Either way, scientology is a religion/cult that has some wild history. The jist of it is that essentially human spirits are immortal and have lived countless lives (aliens are involved also and Xenu is a big galactic baddy)
scientologist just means someone who's in the cult, someone whose profession is science is a scientist
translator probably just got it fucked up
