Purpose of Lightning Network

[tokenpool]

I've heard a lot about this lightning network, and how it works, however I have questions on the purposes of it.
From what I know, much of Bitcoin's value comes from the technology behind it, the blockchain. This allows everyone and anyone to know exactly where anything and everything is at any given time. That to me was the purpose of the coin.
All of that is eliminated with the lighting network.

Why are people so excited about the future of the lightning network. (I think a full P2P token has great potential) but it seems to be against everything that Bitcoin was originally built upon and the technology that is helping push Bitcoin's value.

It is for everyday use.
Lightning network to the mainnet, is like PayPal to the bank.
