Because the standard says so.

Answer from William Entriken on Stack ExchangeHello,
My NFT activity shows Minted but from Null Address. Was it successfully minted?
How will I know when my nft was successfully minted?
Thank you

Hey! I am trying find out who is holding the game specific nfts on etherscan. While searching, I saw null address that holds nfts. Then, I searched online and it happens to be that somebody accidentally sent to wrong address. However, when I looked at the inventory of null address, I saw these are newly minted nfts and there is no other transaction. On the transactions it says nft is transferred to some other addresses however I can't find the tokens on those addresses as well. I feel lost now, any explanation is highly appreciated. Thanks in advance!

It always says that when you mint.
hello, sometimes i see a transaction with a value X from NULL address 0x0000000000000000000000000000000000000000 arriving to my wallet that gathers suspicious tokens like this one https://bscscan.com/token/0x4ac52588a1e762dc285bcc957874a3688296f711
