Still, that doesn’t prove that they are ghosts does it? I mean, it still could just be people standing round an old jeep with the bonnet up (and I must admit that I’ve failed to see anything at the point you indicate that looks like that to me).
Sorry, you’ll have to excuse me, I’m a born sceptic (and it’s nothing personal) but to prove that these are ghosts wouldn’t they have to be seen clearly and then do something ‘ghostly’ like disappear as in the original account. The problem then is that a ‘disappearance’ on film (or video) can be easily done with special effects (not even that special these days) so again you’d need something more to prove it.
It all begs the question how do you prove ghosts exist without actually seeing one in person?
