Do ghosts and ufo really exists?

I believe that everyone has thier own opinions on this subject and also that if you believe in ghosts / spirits / aliens then that is what exists for you.... (if that makes sense) I believe in Ghosts / Spirits and I have had some encounters myslef with them. As for Aliens I am not too sure although I have a feeling we on earth are not the only lifeforms out there...

no. There are no ghosts because when you die you go to sleep. Aliens. well have you ever seen one. Most normal people havn't.
