Attempts to create a naturalistic cosmogony are subject to two separate limitations. One is based in the philosophy of science and the epistemological constraints of science itself, especially with regards to whether scientific inquiry can ask questions of "why" the universe exists. Another more pragmatic problem is that there is no physical model that can explain the earliest moments of the universe's existence because of a lack of a consistent theory of quantum gravity. Also of interest are supernatural creation accounts, as in ancient Greek myth or in the Creationism of the Abrahamic religions.
An ancient consumerist winter holiday. Unlike Christmas and others, it has no particular religious origin and is completely secular. Celebration involves the purchase of Cosmopolitan Magazine and Egg Nog. Participants drink the latter while dramatically reading the former, learning great sex tips and a variety of whimsical names for vaginas. An additional practice that is less well-known involves the purchase and eating of Swedish Fish, often intended for those who do not enjoy Egg Nog.
