Yep! Actually there are 3 different first transaction in bitcoin history.

[1] Peer to peer transaction which is the 10 BTC sent from satoshi to Hal Finney.
[2] Crypto to Fiat transaction when Sirius sold an amount of BTC 5,050 for $ 5. LOL, if anyone who's a time traveller or can foresee a future  
[3] Real world transaction is when Laszlo buys 2 pizza for BTC 10k. It was Papa John's pizza
