Why do people still believe in religions?

For example, almost all my family members, relatives etc. are still muslims and they believe that Quran is the word of the God, even though they never reviewed or read it, but I read it in 3 different languages and always questioned and realized that it is just a comedy fairytales book which has lots of errors and violence.

And according to them, I will be burn in hell and they are going to heaven and fuck 72 virgins and drink wine all the time.

Why in the great information age, people are still not waking up.
