Bingo. Craig explicitly states early in the book that by ‘Adam’ he means both Adam and Eve. I think this is an unfortunate choice to start with, given the prominent role of Eve has played in Christian arguments for women’s subordination and inferiority. Simply removing her from your theological account of the origin of humanity is not a good look.
I think Eve’s erasure also leads to a logical gap in Craig’s argument. The Garden story is basically myth, and Adam is only necessary because of Paul’s words in Romans. Okay. But Paul doesn’t say anything about Eve there, so why is she needed? And yet Craig brings her back in as a historical figure when he’s putting his final model together, describing a pair of hominins who are made human by divine action, with no justification. He seems to have literally not given her a second thought.
