The statement that is INCORRECT about Cosmic Microwave Background (CMB) radiation is:
"it appeared only a few years ago."
The CMB radiation is a remnant from the Big Bang and has been present since approximately 380,000 years after the event, not just a few years ago. The other statements about its uniform temperature and existence as electromagnetic radiation from the Big Bang are correct.
