The definition of magic is: the power of apparently influencing the course of events by using mysterious or supernatural forces."
God is supernatural, if he wasn't there is no way he could exist. So by definition God is magic, or magical and he therefore performs magic. Like creating the universe by hand and trees that when you eat their fruit makes you wise or other magical things. Therefore this is true.
Then religious miracles are not the greatest magic tricks. Why? Because no religious miracle has actually occurred in history, yet magic tricks have. Magic tricks can be explained with a simple logical process which can be supported by science. They can be conducted by anyone if they know how to, like a scientific experiment. Religious miracles have not occurred, are physically impossible and can only be conducted by specific people, all of whom are fictional.
