damn we are in agreement, appart from the chicken thing. At some point chicken needs to be defined, whatever definition you place on it, providing it's somewhere after T-rex, it was born from an egg. Whatever laid the egg that hatched into the first chicken, cannot have been a chicken or that would have been the first chicken, which itself hatched from an egg. However the term chicken is defined, I think we can agree upon what an egg is, and therefore the first chicken hatched from an egg that already existed. Therefore the egg came first. damn, now I think we're going to agree on everything.
