Something that has existed for a long time but its age is less than a month

Answer:
The concept of a “newborn baby” fits the description of something that has existed for a long time in terms of human history, yet its age is less than a month. Newborn babies are a common occurrence throughout history but individually are less than a month old. This paradoxical nature arises from the fact that while babies have been born throughout the ages, each individual baby’s lifespan is counted in days, weeks, and months. Therefore, a newborn baby encapsulates the essence of a long-existing phenomenon while being extremely young in terms of its own age.
