The comparisons to God are a bit annoying. A psychic dosent have to be God to do a good job--which means having some sort of consistency providing insight and predicting the future.
Lawyers, doctors, teachers, nurses arnt God, but they better do a fairly decent job if they want to keep their license. Free will is real, but too many psychics use it as an excuse whhen they know that they are just guessing outcomes. Seriously, a lot of wrong predictions are guesses and made up BS.
