Why Do People Still Believe In Ghosts?

I'm still on my Idea about aliens and ghosts.
These are the creatures of the other world, the invisible world.
They have their life, but sometimes some evil one of them try to make people scared and confused. They have super powers to turn their shape and they do that to make us believe this. Once and again take the fear out of your mind by asking the god to make your mind clean and peaceful.

Jesus knew that ghosts existed. A ghost is simply a spirit. Jesus sent the Holy Spirit/Holy Ghost to his believers after He ascended into heaven. The other spirits are not Holy.

Mark 64:49When the disciples saw Jesus walking on the water, they thought he was a ghost, I:and they started screaming. 50All of them saw him and were terrified. But at that same time he said, "Don't worry! I am Jesus. Don't be afraid."

Luke 24:35 Then the two from Emmaus told their story of how Jesus had appeared to them as they were walking along the road, and how they had recognized him as he was breaking the bread. 36 And just as they were telling about it, Jesus himself was suddenly standing there among them. "Peace be with you," he said. 37 But the whole group was startled and frightened, Thinking they were seeing a ghost!
]38 "Why are you frightened?" he asked. "Why are your hearts filled with doubt? 39 Look at my hands. Look at my feet. You can see that it's really me. Touch me and make sure that I am not a ghost, because ghosts don't have bodies, as you see that I do." 40 As he spoke, he showed them his hands and his feet. (that were pierced)

Even though we live in the C21,many, many people in all cultures are open to the possiblity that there is another life in which people live after their death. This belief is strengthened by  'near death experiences' reported from all over the world.

Many cultures still believe that at certain times of the year their ancestors come back to this life and various rituals are performed to appease these spirits. In some South American countries dinners and celebrations are held to which it is believed that the ancestors visit and join in the festivals.

In pre-history the spirits of the ancestors were almost certainally part and parcel of everyday life and no great distinction was made between the living world and that of the dead. Excavations at many archaeological sites seem to confirm the latter.

People experience many sitings or feelings which they claim to be ghosts or souls and who are we to argue with their experiences? think of the last time you visited a creepy ruin and felt that someone was watching you....
