Which chapter and verse says that?
Gene 2:19 (KJV) And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought [them] unto Adam to see what he would call them: and whatsoever Adam called every living creature, that was the name thereof.
I would assume that since the man called the animals names he was speaking.
