Changes

* The [[Earth]]'s magnetism is changing at too fast a rate for the Earth to be old.  The Earth's [[magnetic field]] is weakening in strength by 5% every 100 years<ref>[http://image.gsfc.nasa.gov/poetry/tour/AAmag.html Earth's Magnetic Field and its Changes in Time], from [[NASA]]</ref>.  [[Exponential decay]] at that rate is not compatible with an old Earth, since it would have required the Earth's magnetic field to be impossibly large at the times postulated by old-Earth theory.

* the age of onset of [[sexual maturity]] is rapidly changing, suggesting that life is in a short-term rather than long-term equilibrium<ref>For evidence of a rapidly changing age for sexual maturity in fish, see http://icesjms.oxfordjournals.org/cgi/content/abstract/46/3/235</ref>

* the high observed rate of [[extinctions of species]] and harmful [[genetic mutation]]s suggest a relatively short period for the existence of life rather than a long one.

* the plentiful supply of high concentrations of underground well water, which would be expected based on familiar principles of [[entropy]] to dissipate over a long period of time.
