You're technically correct regarding carbon dating not being able to date into the millions of years. Carbon dating is useful up to about 45,000 years into the past. Other forms of radiometric dating (they're all popularly referred to as carbon dating, even though they are not) have other ranges in which they are most accurate. Uranium-lead radiometric dating, for example, can date rocks up to 3 billion years old with only a 2 million year range of error.
