Satoshi, regardless if he's a name of a team or just one person, didn't write all of these codes overnight. He needed a lot of time to make all of these. To open up a new world, to implement his own concept. It's even possible that Satoshi have thought of this decentralized network when he was still young and then studied to master programming to realize his idea.
I've thought so too. Due to the robustness of Bitcoin's system, it would've taken several days or even months to get it accomplished by a single person. That is why it kept me thinking of whenever Satoshi would've been a group of people, instead of a single person. Still, it could exist the possibility of it being designed by a single person, but again it, would take quite a long time before getting it done.
Nevertheless, the most important thing is who Satoshi is, but what he really made. He made a revolutionary technology that will change our lives for the better, giving us the opportunity to get control of our own money, instead of leaving it into the hands of greedy bankers, or middlemen. Just my opinion.
