Opinion as Fact

So, I read this in the article about the Space Shuttle landing at Edwards Air Force Base, about 30 miles from Lancaster. Specifically, it was talking about the repairs the crew did on the Hubble Space Telescope:

...The replacement camera and other new instruments will enable Hubble to peer deeper into the universe, to within 500 million to 600 million years of creation....

I wish people wouldn't use these types of statements when talking about the universe. they make it sound like it is a fact, when there is NO PROOF that the earth is billions of years old, just like there is no PROOF that the world is only about 6000 years old, as I believe.
