Do you believe in Ghosts?// I DON'T

Hi everyone one, well i have been asked so many times by people that do i believe in Ghosts and my answer to them is always no.

Mostly in movies and in stories ghost are said to be dead person who rise from death, either to hunt and kill people who are the cause of their life or something like that.
For an example in movies, a boyfreid kills his girlfriend just because they have been together for so many years and she decided to cheat with his best friend. After which she turns into a ghost and comes back to hunt him. Also it might be an innocent person walking down the road home then suddenly he got attacked by a thief, the thief steals from him and then kills him, whereas he also rises and comes back as ghost looking for the thief to also kill him.

Imagine what happens in movies or the stories being told to us about ghost was to be associated to real life stories almost every person will be hunted by someone who thinks they are the cause of their death, just take a look at this:
an innocent doctor trying to save a patients life who had a seriouse accident which was caused by him over speeding and then ramming or crushing his car into a tree. In this kind of scenario you can't convince me to accept the fact despite the doctor wasn't able to save that person so he should becomea ghost and come and hunt him for failing to save his life where by he is the cause if his own death.
THAT IS SIMPLE WHY I DON'T BELIEVE IN GHOSTS
