Nobody has EVER proved they have seen a ghost. So the answer is no-one.
It's hard to tell for, if say when the second person on earth saw the ghost of the first person on eath, the third might not belive them, so the person who 'saw' the ghost may think it was a trick of the mind, any way the debate still gose on wether they are real or not...

Who could ever say they saw the first ghost that was ever sighted, I suppose a lot of us would actually wonder if what you saw was infact a ghost or a figment of your imagination, if a ghost was ever first sighted you would probably have to go back to cavemen days, maybe he saw a ghost dinosaur!!

.the first person who saw a vampire was SHELLU McARTHUR
the first person who landed on the moon saw moon rocks the first minute he collected them
There are three perspectives - first person (I saw, I observed, I went), second person (you saw, you observed, you went), and third person (he saw, he observed, he went).
Depends on how you want to do it. Usually the person who saw it first gets the Easter egg.
