Not a good "start" today

[Fatal070]

So I wake up at... let's say around 11am. Went and took a shower and what not and was getting ready to go to class, but before I leave I always start my car, so I go out and the ****** won't turn over! :o
The battery is fine I tried jumping it for the hell of it... no luck (I'm not sure why I tried that I mean I was getting perfect power just no start) I could hear everything working fuel etc but it won't start... I'm thinking starter... so now my car sits in my yard... o well tell me what you all think
