Anyone who has a PhD in one area and uses it to justify their views on another is an idiot.
As Heinlein noted:
Expertise in one field does not carry over into other fields. But experts often think so. The narrower their field of knowledge the more likely they are to think so.
Robert A. Heinlein, Time Enough for Love, 1973
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
