People are confidently saying that the egg came first. But the answer really depends on the askers definition of what a “chicken egg” is. Is it an egg that a chicken hatches out of? Or is it an egg, laid by a chicken? If it’s the former, then yes the egg came first. If it’s the later, then the chicken came first.
And if you use both definitions: “a chicken hatches (exclusively) from an egg” and “an egg is laid (exclusively) by a chicken”, then it is an example of circular reasoning.
