The design and coding started in 2007.

Well it is speculated that Satoshi had posted on an internet forum about the concept of bitcoin in the early 2000's, around the time that paypal first came out.

As Cryddit says, we don't know for sure. Of all the possibilities though, I strongly favour the idea that Satoshi was simply telling the truth.

How long have you been working on this design Satoshi? It seems very well thought out, not the kind of thing you just sit down and code up without doing a lot of brainstorming and discussion on it first. Everyone has the obvious questions looking for holes in it but it is holding up well

Since 2007. At some point I became convinced there was a way to do this without any trust required at all and couldn't resist to keep thinking about it. Much more of the work was designing than coding.

Fortunately, so far all the issues raised have been things I previously considered and planned for.

Given the design and code at the time I have no good reason to doubt this.
