According to Ovid's account of creation in Book I, when God first created the Earth and all the things on it, there were no human beings. All the other animals had been made, but not human beings. So, at that point, God made human beings. They were animals too, of course, but they were different from all the other kinds of animals.
Ovid says that man was "of a more exalted kind" than the other animals. Man was made with "particles of heavenly fire." In other words, God put parts of his own divinity into human beings and this distinguished them from the other animals. It made them able to think, more caring, and it made them fit to rule over the rest of creation.
