God is fiction, just like every other bronze age deity. Judaism, Christianity, Islam all worship the same deity, they just have slightly diferent rules and cherry pick the testaments differently. Gods are an easy way for humanity to explain things that are unexplainable, like lightning, when knowledge and science are not advanced enough yet to explain it, hence why cultures create deities (but not the same deity). There can be no argument for the Jewish god that cannot be made for Zeus or Thor. Faith in god is inherently illogicalas it involves believing in sometime with no evidence to support and tons of evidence to the contrary.
