Why history keeps repeating itself?

The concept of history repeating itself is a very well known concept known as 'Historic Recurrence". Many have speculated that the world events are stuck in a strict cyclic manner where many events are bound to happen again with shocking similarity. However, this can't be said to be entirely true. However, some scientists believe that the reason history seems to repeat itself is due to multiple independent discovery, or the idea that many people think of and discover the same things independent of each other. This results in the same courses of action taking place in different times and places.
