Why are Bitcoin transactions stored ?

The point of crypto currency creation was for the reason of privacy, which was coated as the word decentralized network, where there's no third party in-between, just the sender and the receiver. Them why are transactions history store and made public, so there can be traceable? Because with this it doesn't feel private to me.

The original purpose of Bitcoin wasn't privacy, but rather a new kind of money where you could send money directly, without intermediaries, through a decentralized and censorship-resistant network. Bitcoin was designed as a decentralized digital currency, its primary focus not on absolute privacy where you could obfuscate your transactions, but rather on financial freedom as an alternative to the fiat system.
However, Bitcoin is pseudonymous, so even though transactions are recorded on the blockchain, the identity of the address owner isn't immediately visible. This can be said to enhance your privacy. Unless you link the wallet address to KYC on an exchange that would break that layer of pseudonymity.

The creation of Bitcoin is not because the author wanted privacy, but rather to have a direct transaction from one person to another person, removing the third party that thrives on fees. If we look at the Bitcoin whitepaper, there is no line that say it is created for privacy, but rather to be censorship resistant.  This means it is created to work without banks or any centralized authority.

Aside from that, Bitcoin is created to be pseudo-anonymous, meaning the identity of the person who does the transaction can remain unknown (as long as they don't link it to their identity), but the transactions are fully transparent to the public.

The reason for this is for transparency to avoid manipulation

And Crypto currency was not primarily for privacy, privacy is like the second reason for the introduction of crypto currency.

Yeah, Bitcoin record every transaction on every blockchain so that everyone could see the amount and address, thus actually protecting the network from double spending and fraud without any 3rd partis interference. Whatever Ledger will never ask your private data like name, DOB or country. So it could not provide your personal detail to anyone, it could only show alias cryptographic addresse

If you do not link your real identity then third parties will not automatically know that it is you. Bitcoin is public but uses an alias, so its not private or anonymous, its pseudonymous
