It is the cosmic ray collisions and neutron-capture involving atmospheric nitrogen.

Natural carbon-14 is formed in the upper atmosphere when cosmic rays collide with nitrogen atoms, producing carbon-14 isotopes. This radioactive isotope then mixes with carbon dioxide in the atmosphere and is taken up by living organisms through photosynthesis, becoming part of their tissue.

Yes the sun is a natural source i read it
An artifact is found that some are claiming is 30000 years old 3.1 percent of the original carbon14 is present The halflife of carbon14 is 5730 year?
Yes, but the dating is only off a little (500 years or so).

Yes. Candle is as natural source of light as the sun is.
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
