Since its founding in 1952, the Church of Scientology has become one of the most ridiculous religions. The religion was founded by American author L. Ron Hubbard. It is well known that Scientologists believe that the Earth is inhabited by extraterrestrial "thetans" who go disguised as humans through our world, and that the "auditing" process is the body of this thetan and the "mental implants" that they give us all will impose, clarify. It is also said that humans have evolved from shells. 
That sounds pretty crazy, right? Despite the ongoing criticism of Scientology, all of the following celebrities are dedicated followers and have expressed their true devotion to the Church. John Travolta
The Hollywood star John Travolta has been a supporter of the Church of Michigan Scientology since 1975 and is one of the most prominent members. Together with his wife Kelly Preston, he tells the church that she was standing next to them when they lost their son after he had a seizure at the age of 16.
Travolta said, "The church has not left a page for two years. I do not know if I could have done it without their support. He added, "The truth is, I did not know if I could do it. Life was no longer interesting to me, so I needed a lot to improve.
Former Scientology spokesman Mike Rinder claimed in an interview that the church has much more control over the lives of Travolta and his family than the public knows about it. He revealed, "Kelly is a much more dedicated Scientologist than John. Scientology dictates every choice in life and informs every decision a Scientologist makes. 
9 Kirstie Alley
Kirstie Alley has been a loyal follower of Scientology since 1979. She had previously grown up as a Methodist. Alley herself admitted to joining the church as she struggled with cocaine addiction. She underwent the Scientology drug treatment program called Narconon and has since terminated her dependence.
Following the filming of the Las Vegas Strip in 2017, she wrote a series of tweets blaming actor Stephen Paddock's actions for psychiatric drugs – a presumption that her testimony came before the coroner's report. The Church of Scientology claims that drugs damage a person's physical, mental and spiritual wellbeing. Instead, they recommend one of their international drug rehabilitation centers in Narconon.
Alley has defended the church against those who condemn their practices, claiming that most of the criticisms do not apply. In an interview, she said, "I think all religions sound bizarre to people who are not practitioners. [ . . . ] For me, [Scientology] is so normal, and probably 90 percent of the crazy stuff I hear is not true. "
