Comets wouldn't have lasted in an old universe (Talk.Origins)

Claim CE261:


 * Comets lose material as they near the sun. If the solar system were very old, comets would long ago have evaporated.

CreationWiki response:

This is not based on observation, but is actually two theories invented to save the old age model from reality. There is absolutely no observational evidence for the so-called Oort cloud, and so-called Kuiper belt objects are too big to be comets and many clearly have a different composition from comets.
