How do Jehovah's Witnesses work around the texts in Genesis 1:26-27 in the NWT Bible?

Its talking about Jehovah (God) and his son Jesus. Jesus was his first creation, so it only makes sense that he was with him when he created Adam and Eve. He created man in "their" image, and Jesus was created in God's image, so it makes sense that in verse 27 it says "his image."
