What actually is the real difference between "create" and "mint"-functions?

[MrsBookik]

I wonder what the final reason is to distinguish between create and mint?

In both cases a NFT gets minted, right? But in create a creator will be stored, while in mint not.

I also could not find any relation to the official ERC1155-drafts nor any relation to the Implementation of OpenZeppelin.

Is this required for the integration into OpenSea to get listed or what is the reason?
