This never seemed to make much sense even when I was a Christian. If we went to heaven/hell when we died, how is it that so many people said their families/friends visited them as ghosts? The two ideas do seem very compatible: earth-located ghosts of past individuals vs. they should be in after-life locations.

The "solution" as my parents seemed to believe, was that most ghosts were demons. This somehow was supposed to help resolve the question.

Ghosts, and gods, and demons, and angels dancing on the head of a pin, and aliens (well, maybe not aliens). Sorry, don't believe in any of it.

Casper is very friendly, just crappy movies. I'd love to hear people's responses though!

The last ghost i saw was shaped like a sphere with many lights shining. it was floating in the air and circling slowly around it's axis in front of me. when i placed my hand within the sphere it felt slightly warmer. i am not sure how long it was there, but i believed it was less than minutes it was very beautiful and relaxing. not really sure if that was a ghost, but it was neat.

I have seen ghosts, but i am not sure how interact with them. they appear in different shapes. i saw one sitting by the river as i waited for the ship around midnight. i asked him a few questions, but he never answered another person came by and spoke him we saw the ship getting nearer and the guy sitting just disappeared. the locals later explained us that a young man drowned the previous year in that area. it must have been him.

I believe, mainly because there isn't a satisfactory answer against it. Once science has a better answer, I will defer to that.

I think it's possible but only in the realm of thermodynamics whereas energy can't be destroyed. "Ghosts" in my understanding is just energy released from the passing of a living being waiting to be repurposed.
Downside to this is that in the same process could hold for the argument that dead people power your toaster. Just a random thought.

Well based upon something that was told to by mother and great grandmother about something I did as a kid, yes I do. I was too young to remember it but apparently I described my great grandmother’s grandfather perfectly down to the tiny blemish on his face.

It's interesting to me - particularly since I embrace science - that one would ask why I "believe" in ghosts. The definition of ghost: an apparition of a dead person that is believed to appear or become manifest to the living, typically as a nebulous image. Let's just start there. Science teaches us that energy cannot be created or destroyed, right? If we are able to detect an image of a person whose energy can neither be created or destroyed, and then that image is mythologized and capitalized upon - is the detection itself invalidated? Asking for a friend.
