Science is about adjusting your beliefs to fit observations. I do not believe in gods nor ghosts because I have never observed them, nor have I been convinced by the records of those who claim to have observed them. Should that change, I will adjust my beliefs accordingly. Science is about the possible, not the impossible.

“I can guess your sign in 12 tries.”

“A scorpio, eh? Let me guess: you breathe oxygen, and enjoy things you like. Your horoscope says to trust people, unless they’re untrustworthy.”
