Special Teams. Defense is off the field at this point.
You can attempt a field goal after scoring a touchdown, or on any fourth down play within you range
If the defense blocks a field goal attempt and is able to pick up the ball and return it to the end zone it is a touchdown. It would be considered the same as if they picked up a fumble and returned it for a touchdown. Therefore it is worth 6 points.
Yes, the defense can return a missed field goal for a touchdown. However, the touchdown would be credited to the special teams and not to the defense since a field goal is considered a special teams play. The TD would be considered under the heading 'return of a missed field goal' and not a blocked kick nor punt return.
The objective of the game is to be the team to score the most points between 2 teams. You score by passing for a touchdown, running for a touchdown (both offense), interception return for a touchdown(defense) fumble recovery return touchdown (defense) safety (defense, the defense sacks the quarterback or tackles the ballcarrier in their own endzone) field goal (special teams, a kicker kicks the ball through the goalposts) extra point (kicker kicks ball through goalposts after a touchdown).
A field goal (kicking the ball through the uprights at the end of the field) is worth 3 points in American football. There is no "point after" attempt for a field goal. In contrast, a touchdown (carrying the ball past the goal line) is worth 6 points and allows an attempt for an additional point after touchdown, which closely resembles a field goal.
If a player catches a missed field goal attempt while in the field of play, he can return it for a touchdown, resulting in six points. After the touchdown, his team may kick the PAT (Point After Touchdown) and score another one point, or convert the two point conversion for two points.

Because after a touchdown, the player will kick into a field goal to 1 point.
after a touchdown
the goal posts are the same as referees; they're considered part of the field. For example, a pass that is incomplete by hitting the ground is ruled a dead ball. So if you hit the referee with the ball with a pass it is a dead ball same with the goal post.
From an Offensive Stance: Tony Dorsett of the Dallas Cowboys rushed for a 99 yard TD in a game against the Minnesota Vikings in 1983. From a Defensive Stance: Antonio Cromartie of the San Diego Chargers caught a Minnesota Vikings failed field goal attempt in the back of his own endzone and ran it all the way down the field to score a 109-yard touchdown - the longest in NFL history.
