False premis as it has not been proven through science.
Would you like me to direct the flood of studies SINCE THE 1950's UP TO TODAY to your direct email? Then you could pick and choose which of the scientists you agree with, and which you disagree with.
A false premise is that which leads to an unsupportable conclusion, or a conclusion that is demonstrably incorrect.
Which exact false premise are you concerned about while trying to answer the question: Do you believe in the efficacy of prayer, as proven by SCIENCE, or not?
Oh, and by the way, answering a question is a time-dishonored tradition for those who have no interest in pursuing a line of inquiry in an honest and open-minded fashion (isn't that what scientists always criticize Creationists for ?).
