Satoshi has many contributors. In my view, he/she is not one person but many. Why, because it would take a genius with multiple skills, e.g. engineering, programming, cryptography, mathematics, financial knowledge and a lot of time, a lotta time to come up with something like this.

It is more plausible that Satoshi was a rogue AI, ET, the Illuminati or future time traveler instead of one single person :)
