→Age of the Milky Way
Non-creationists believe that the cosmic microwave background indicates the first stars were formed 200 million years after the [[Big Bang]], and that the Milky Way was among the first galaxies in the early universe. They believe it is 13.6 billion years old, within 800 million years. This estimate was calculated by measuring the amount of [[beryllium]] in two stars within the cluster NGC 6397,<ref>http://arxiv.org/abs/astro-ph/0411699</ref> which under their assumptions gave an age of 13.4 billion years. They then added 200 million years to this estimate for their belief that beryllium takes this long to form.<ref>http://www.universetoday.com/2004/08/22/estimating-the-age-of-the-milky-way/</ref>.

[[Creation science|Many other scientists]] disagree and highlight the many problems with this model<ref>http://www.pathlights.com/ce_encyclopedia/Encyclopedia/03-ss5.htm</ref>. Debate continues on this topic in scientific communities.

Current models of galactic formation in big bang theory cannot explain observed galactic phenomenon<ref>http://www.answersingenesis.org/creation/v26/i3/galaxies.asp</ref>, and the cosmic microwave background, hailed as proof of the big bang and used to calculate the age of the Milky Way, has proven to be something else entirely<ref>http://www.moondaily.com/reports/Big_Bang_Afterglow_Fails_An_Intergalactic_Shadow_Test_999.html</ref>.
