gosh.... i really don't believe in ghosts. The deffinition of ghost is an absurity in itself, a physical imposibility.
2] (hey .. what happend to 1?? ) ghosts and religion (heaven) cannot be both true at the same time.
3] in order to see/hear/smell/talk, a ghost would need eyes/ears/nose/mouth+lungs+vocal cords. Having neither, it is the invisible equivalent of a vegetable. Who knows, maybe the tomato you just ate was elaborating a warp [faster than light for the non-star-trekers] engine
4] i do not believe in religion (incl. god) either. Don't want to give the full arguments, suffice it to say the entire christian doctrine is based on false assumptions.
5] ghosts are supposed to be the souls of the dead, BUT, when someone dies, his/her memory is VANISHED, therefore it is abruptly ilogical to assume that person will haunt his house.
6] in order to do real interaction with the physical world, a 'form of energy' shoul be extremly powerfull, and being that powefull would be struck down at the first lightning in a 20 mile area. [prove me i'm wrong...]
7] 'santa claus' EXISTS in every parent, it's a symbol of kindness, and of sacrifice, because what won't a parrent do to see his kids happy on Christmas? [PS: no, i don't believe in christmas' motive [jesus and stuff] either, but this doesn't mean i miss a good time when i see one].
8] *gathering my limbs from the floor after some obscure force jerked the chair from underneath me and smashed it in my head* ***pointing out the EXTRORDINARY REALISM of the situation
*** - > if you really want to believe in something, believe in yourselves, in happiness, in your lover, in sex... (why not). After all, since we are all supposed to be descendents of Adam and Eve, and our really long time-ago-ancestors were having a tremendous number of incestuous relatioships to be able to expand the species, i can safely say i am nuts. and i love it.
ps: ghosts' cant' have sex for obviosly painful reasons...
***>edit<***
it was supposed to be PAINFULLY OBVIOUS, but i guess it came out the other way arround ...
