Who wrote the first issue of superman batman?

The question asks for the writer of the first comic issue that includes both Superman and Batman. The only verified information available concerns the 2016 film Batman v Superman: Dawn of Justice, which was written by Chris Terrio and David S. Goyer and directed by Zack Snyder. No evidence in the supplied sources identifies a comic writer or the specific issue number that first paired the two characters. Consequently, based on the available evidence, it cannot be determined who wrote that comic issue.
