The hen came first..
how can u say so?
micro organisms came first then they went on evolving according to the surrounding or you can say habitat then after that some aqatic animals came in this world and one of the oldest creature on earth is existing since dinosaurs' period that is a some kind of tortoise.
and gradually evolving like that according to me hen and rooster and then egg and after that chick which is obvoious.
sorrry it's obvious
The hen.....................
No not hen coz JBS haldane proved that in past due to lightining on the earth the gases on earth ammonia,sulphide etc in the prescence of lightining they formed complex carbon compounds by this we can say that egg came first as it contains calciym
