The Old Stone Age or Paleolithic era, roughly spans from 2.6 million years ago to about 10,000 years ago. During this time, humans relied on hunting and gathering for food, lived in small nomadic groups, and used stone tools and weapons. They did not have the knowledge of agriculture, so their survival was highly dependent on the availability of natural resources in their immediate surroundings.
On the other hand, the "New Age" is not a well-defined term, but it broadly refers to a cultural movement that emerged in the 1960s and incorporates elements of various ancient traditions, spirituality, alternative healing practices, and self-discovery. It does not have a specific time period or geographical location associated with it.
