The chicken came before the egg.

To make your life easier, I do not believe the creation story, and will be aruging only from the standpoint that takes evolution into account. What I mean was "come from an egg", I apologize. http://www.sciencemag.org... "Small globular fossils known as Olivooides and Markuelia from basal Cambrian rocks in China and Siberia, respectively, contain directly developing embryos of metazoans. Fossilization is due to early diagenetic phosphatization. A nearly full developmental sequence of Olivooides can be observed, from late embryonic stages still within an egg membrane, to hatched specimens belonging to several ontogenetic stages. Earlier cleavage stages also occur, but cannot be identified to taxon. Olivooides shows similarities to coronate scyphozoans and to their probable Paleozoic representatives, the conulariids. Markuelia eggs contain looped embryos of a segmented worm with short, conical processes covering the body. " S.

Here we report for the first time egg clusters in a fine-grained siliciclastic matrix from the Middle Cambrian Kaili Formation lagerstï¿½tte (513–501 Ma), south China. Some were imaged under synchrotron radiation. These spheroids are preferentially preserved as microcrystalline quartz and interpreted as marine invertebrate fossil eggs based on patterns of spheroid arrangement, shape, and analogues of fossil and modern invertebrate eggs. Embryos with cleavage cells are evident in at least one cluster. Detailed element analyses show that eggs are primarily preserved as solid silica replacement, and there is a calcite layer covering the eggs replacing the original organic layer. Silicification of intact invertebrate egg clusters is reported here as a new mode of preservation associated with a Burgess Shale–type deposit. " You said in your opening statement: "I say that the chicken had to have came before the egg". You make no specific reference to a chicken egg, so I can understand from this that you are suggesting the chicken species came about before eggs did. The common chicken which I assume you are referring to (Gallus Gallus Domesticus) came from the Red Junglefowl (Gallus Gallus) which was domesticated and over many years became the chicken. Speciation would not occur in the original predecessor of the chicken, the Red Junglefowl, only in its offspring, with enough variation to classify it as a separate species. The offspring would have come from the egg; therefore the egg came before the chicken.
