Answers in Genesis is a well known young-earth creationist website that says the Universe is less than 6000 years old. I was referred to this article: http://www.answersingenesis.org/tj/v18/i2/echoes.asp" [Broken] by a creationist whom I was debating with. Now, my major interest is in biology and I was wondering if you could help me decipher what the article is about. I remember a few years back when the WMAP and even earlier the COBE pinpointed minor fluctuations within the CMB radiation. Aren't the AIG guys saying the same thing here? How is this challenging the Big Bang theory at all? My confusion is a combination of my poor understanding of cosmology and creationism obscurity. Any help would be gratefully appreciated.
