Correction d'anglais !!

[olivthill]

Some persons have seen ghosts but not me thus I do not believe in them ! Maybe if I had seen them, I would believe in their existence.
I don't think that Extra-terrestrials exist because I think that if they would exist they would have already shown themselves!
I think that supernatural beings exist in science fiction!

Si l'on considère que les hommes sont encore majoritairement des barbares, on peut penser que les hommes ne seraient pas dignes d'être visités par des extra-terrestres, et on pourrait dire :
"Les extra-terrestres existent, la preuve, c'est qu'ils ne se montrent pas !"

Pas d'accord avec le tout premier.

Some persons have seen/saw (dépend vraiment du contexte. Ils ont vu et voient toujours, ou ils ont vu tout court?) ghosts but not me thus I do not believe in them ! Maybe if I had seen them, I would believe in their existence.
I don't think that Extra-terrestrials exist because I think that if they existed they would have already shown themselves!
