This is retarded. 1. Birds evolved from lizards.
2. Lizards lay eggs. So at whatever generational cutoff point you pick to say “here's a lizard who had a bird,” there was still an egg evolved. Eggs were around way before birds were. The egg came first.

Is that obvious? Well except for christians who will problably tell you that it's their imaginary friend God, who did it. :)

So the chicken and the egg are lying in bed together and the egg lights up a cigarette and looks to the chicken and says “well I guess that answers that question.”

Dinosaurs.
