How old is the Earth?!

ok, i'm not going to get in to the scientifics of how old the earth is becuase i really dont think it matters much. i realize a lot of christians are young earth. i am a christian i am old earth. yes, i am creationist, but i am old earth. the bible does not say when the earth was created, so, i believe it could have been around a while before the bible was written. here, i'll quote from genesis.
"In the beginning God created the heavens and the earth.
2 Now the earth was [1] formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters." after these two verses it goes into talking about the creation and the 7 days of creation. but it does not put the earth into these 7 days. so therefore, christian/creationist does not equal new earth. since the bible does nothing to support new earth(or old earth for that matter, old earth just seems to be supported by evidence) there is no reason to believe it was created the same time life was created.
