There is a very common example you may have heard from the TV or movie, especially, in horrible movie. When people see something horrible, usually they will say "What the hell...?" Thus, there is an evidence that hell does exist in the living world.

Yes, I believe the existence of hell and heaven in this mundane world that we are going through now, and existence of the hell and heaven after death too. Why sometimes we have to suffer like hell? And sometimes we enjoy happiness? To explain the reasons, we need to have some Dharma Talks then.
Buddhists believe ones had done some good deeds in previous lives/early part of ones' lives, therefore they enjoy happiness/blissful lives.But if ones had done bad things in past lives/ early part of their lives , they may always encounter sufferings in this lives/ later part of their lives. They call it the "force of karma". Thus ones are encouraged to do good deeds now and then to sow good seeds for the future/ next lives in order to reap what you sow.
