No it says nothing about the age of the earth. It does set a minimum age for the universe but you are trying to disprove Young EARTH Creationism, not Young UNIVERSE Creationism.
You might be able to challenge the Genesis 1:1 tale if you could show there was a difference between the age of the universe and the age of the Earth, but again, nothing in your presentation establishes that relationship.
