Why do people mine crypto currencies? I have read many articles and watched videos but I still can't fully understand Bitcoin, mining and blockchains. I understand a block in a blockchain contains data and its resulting hash. I also understand a miner attempts to generate a new hash by hashing the previous hash in the chain with a nonce. A miner will keep trying until they create a hash with required difficulty level.


I think I understand what happens during mining by I don't
understand why we mine? i.e. Yeah I found a block so what? (of
course miners are rewarded but why?) 
How would people use this found block in a real life scenario? 
Is the data in a block a real life scenario data. 


A real life example will be appreciated.

If people are going to down vote please let me know why so I understand?

Miners are rewarded for mining via the block subsidy and the transaction fees (transaction fees are paid to miners). They mine in order to earn that reward; the reward has value and therefore miners will want to get it by mining.

Blocks are not just arbitrary data, they are part of the Bitcoin blockchain and used to store transactions that are considered permanent. They don't have any other use. The point of blocks is to have a permanent transaction history that is guaranteed by the work that miners must do to create the block.

There is no other "real life scenario" or "real life example" to give here for blocks; that's just not how they work.
