What makes it possible for humans to accumulate an amazing amount of information over long periods of time?

social learning

Explanation:

Social learning is perhaps the best way to effectively learn simply by observing other people and noticing their experiences. Since we can see consequences of behaviours it tends to teach us important lessons in life.

Another way is when children are growing they start to imitate and learn by observing others, then model a role. This enables them to gather an amazing amount of information present in the environment in a very short time-lapse. Also, the evolutionists believe that humans have evolved in part because we can learn socially and culturally, making thing from the past still be present today since we first adapted to Earth.
