ELI5: Because the number of babies born is pretty much the same every day, how do we get clear generations?

Not sure how else to phrase this. If the amount of people born every day stays relatively balanced (there aren't drastically more babies born in one month than another), then there is about a balanced amount of people of all ages getting older all the time. So, how do we arrive at generations? If someone is said to be a part of a distinct generation, there will always be lots of people born a few years before and a few years later. Where do they fit? How is the line drawn on something so continuous and always moving?

It's just a generalization - it has no real basis in fact. The Baby Boom, at least, was a period of elevated birthrates from about 1946 to 1964, with the contrast made greater because WW2 was a time of fairly low birthrates, but even then there's plenty to distinguish someone born in 1947 from someone born in 1963. A person born in 1965 would be much closer.

In general, yes, it is continuous. The "generations" are merely a convenient way of speaking about people. Oftentimes the generation names can even be somewhat misleading. For example, people born in the mid 1920s to mid 1940s are often called the "Silent Generation", yet it included Malcolm X, Martin Luther King, Andy Warhol, John Lennon, and Allen Ginsburg, among many others.
