Science can say nothing about the magical world. By definition God is not material, therefore not in the realm of science.
Well, scientific discoveries are still being revealed, and will continue to be way into the future. So at best all you can say is that science is not yet mature enough to measure whether God does or doesn't exist.
Miracles exist. Science is on the record with those:
Dr. Candy Gunther Brown, who earned her doctorate degree at Harvard University, is a professor of religious studies at Indiana University. She has a neutral outlook on religion, having said, “I do not assume the existence or nonexistence of a deity or other suprahuman forces.”
Brown cites two scientific, peer-reviewed studies that confirmed the efficacy of prayer on patients. She noted, “One of the first publicized studies was by Dr. Randolph Byrd, published in 1988, in the peer-reviewed Southern Medical Journal. It was a prospective, randomized, double-blinded, controlled study of four hundred subjects.” The results: “Patients in the prayer group had less congestive heart failure, fewer cardiac arrests, fewer episodes of pneumonia, were less often intubated and ventilated, and needed less diuretic and antibiotic therapy.” The editor of the Journal noted that the study had been peer-reviewed and was judged to be a properly designed and executed scientific investigation.
THEN, a decade or so later, a REPLICATION STUDY by Dr. William S. Harris and colleagues was published in the “Archives of Internal medicine.” Dr. Brown noted of this study, “This was a ‘gold standard’ study of the effects of intercessory prayer on almost a thousand consecutively admitted coronary patients. Half received prayer, the other half didn’t. And again, the group that received prayer had better outcomes than the control group. These studies affirmed that the recipients of prayer had better outcomes than those who didn’t receive prayer.” - "The Case for Miracles," by Lee Strobel, pages 123-128
