I believe in aliens do you believe in extraterrestrial life?
You know, since the mid-1900s there have been ongoing searches for alien life.  I happen to believe in the possibility. 
Yes indeed and I believe they may have been here before us!
I think science fiction might also influence our thinking.  Sci fi has imagined a wide range of possibilities regarding aliens over the years
I agree and movies as well, remember War of the Worlds?
I do.  I also am a fan of Isaac Asimov.  He is considered one of the big three of the science fiction writers
I love his books and grew up reading them all
Asimov actually is credited with over 500 books!
