One of the unique benefits of NFTs is the ability to track every transaction on the blockchain. Every NFT has an owner, creator, history, and this information or "provenance" is verifiable on-chain.
On each item’s page, below the picture there is a section "Details | History" where you can verify details about the contract used to create it.
Clicking History button will reveal:
— Time and date of creation.
— Owner (and previous owners)
— Transaction history and purchase amount.
