Agreed the first transaction was between Satoshi and Hal Finney... but I always wonder what was the first transaction where people actually traded something {service or goods} for Bitcoin? Is this
documented somewhere or was the famous pizza the first? Is a transaction really a transaction, if no goods or service are linked to it? If I transfer money to you as a test, but I do not buy something or
pay for something... would it still be a valid description of the action that took place?
I'm pretty sure that the first actual transaction in exchange for actual goods was the pizza transaction. It's documented right here: https://bitcointalksearch.org/topic/m.1141. In fact, most of Bitcoin's early history is documented right here on this forum. Some of it is also on the cryptography mailing list and IIRC there was also a bitcoin mailing list on sourceforge.documented somewhere or was the famous pizza the first?

i wonder how can hall finney can make the first bitcoin transaction,we know he was not satoshi nakamoto,any explain for this?or hal finney is real satoshi? i think first transaction only made by satoshi nakamoto.
While Satoshi was the one who sent the Bitcoin, it could also have been Hal Finney who sent it. Hal was one of the first people to respond to Satoshi on the cryptography mailing list. He was one of the first developers alongside Satoshi and apparently helped Satoshi a lot during the early days. He even helped Satoshi before Bitcoin was released when Satoshi asked for help on his "project" on the cryptography mailing list. He could very well have mined some of the first couple hundred blocks. 
. Thanks for information bro.
