How to make irony:
First, know that Kansas is the leading producer of helium on Earth, providing 2/3 of the global supply.
Second, understand that most of the helium on Earth comes from a) the breakdown of radioactive nuclei; a process which takes tens of thousands to millions and even billions of years, and b) the Big Bang, 13.7 billion years ago.
Third, note that both these timescales are > 6000 years.
Fourth, mix all the above ingredients. Shake well, and enjoy the delicious irony.
