Do ghosts exist?

[Phazite]

No for me, especially after witnessing the birth, propagation, and modification of ghost experiences.

I vote yes, If you take a picture in some places, like Church or Graveyard, you'll see the orbs.

The orb is the energy being transferred from a source (i.e people) to the spirit so they can manifest. For example,
If you see the picture above, you'll see the things like round balls, that's the orbs.

The problem I have with this is that, even assuming they couldn't be something else such as dust particles, there is no way to know something like this (spirit orbs and such) though. You have to make an assumption (they're spirit orbs) that you have no evidence for, and no reason for besides that it confirms a belief that you already had (or were open to) in hindsight.
