Psychics do exist and some of them don't even know they have this ability.
I have a friend whose Father is always winning at the race track. I asked him did he have some system and he says he just feels it. He could have psychic ability and not even know it like some lottery players might have.
Science also tells us that the future can influence the past. Like Einstein said the distinctions between past, present and future is just a persistent illusion.
