Anyone who claims that Hal Finney was Satoshi Nakamoto should read the research done by James Lopp in which he proved that while Satoshi was active online Hal was on the other hand active in real life running races. Unless Hal had an associate who "played" Satoshi for him, this is very concrete evidence that Hal Finney was not Satoshi.
Yeahh i know it mate but do not underestimate the intelligence of a man who would like to do everything he could to not make himself known
