I read this article on the internet about ancient planets here
http://www.newscientist.com/article/dn26856-ancient-planets-are-almost-as-old-as-the-universe.html?utm_source=NSNS&utm_medium=SOC&utm_campaign=hoot&cmpid=SOC%257CNSNS%257C2014-GLOBAL-hoot#.VMeNxWazWUl here's a quote from it.
"These planets mean it only took the universe a couple billion years to figure out how to build rocky planets, and they've been around for a really long time," says Travis Metcalfe at the Space Science Institute in Boulder, Colorado. While Kepler 444's planets are too hot for life, its age suggests there might be cooler, older worlds elsewhere. "If life needs a long time to develop or lots of places to try to develop, having rocky planets this early in the history of the galaxy means planets with advanced civilisations should be everywhere."
I thought it was interesting and may relate to the thread.
