which came first

Something I don't really get
Which came first, chicken or the egg?
Do scientists actually discuss this shit? Because I swear I can solve it with junior high school knowledge.

The answer is the egg (by evolution)
The answer is chicken (by creationism)

Assumptions from evolution
1) Variations naturally occur in a population.
2) Mutations that will pass onto the child occur in the gametes (e.g. Down syndrome), and not those that affect the adult during his/her lifetime (e.g. lung cancer)
3) Eggs (not necessarily from chickens) existed a long time before the first chicken walked the Earth (various reptiles and birds).

It can be concluded from 2) and 4) that an egg was sitting there, and it hatched into what can be recognised as a chicken. 1) warrants the existence of variation (that doesn't deviate too much from the parent, but has appreciable differences).
By pure logic a duck did not go super-saiyan and turn into a chicken.
The only possible route is non-chicken-parent-bird -> egg -> first bird than can reproduce with the modern chicken.
Like this argument is actually dumb.

However by creationism God made everything and on the 76th (ty Marcus) day he made man. So that really solves stuff quickly too.

Either way, whether you put your money on science or the Old Testament, there's a quick answer.

This is like the time I got mad about comparing apples and oranges. There is nothing easier to compare.
