I know this is crazy base on what people post at the Internet now a days.
Do you actually believe in aliens?
Basing on people's posted video I would say yes what do you think guys? I hope I am not just the one who believes in aliens.
if you believe in religious works, then you can read the book of enoch. it's a non-canonical apocryphal work and is no longer included in today's printed bibles. you'll get to read about aliens there including giants and angels.
