Back in 1871, football matches were decided entirely by goals. In games played under Rugby Laws, touching the ball down over the goal line gave the attacking team a free kick from the goal line where the ball had been touched down, which was then 'marked' by another member of that team, who, in turn was entitled to take a free kick at goal. Once the touchdowns were recognized, they still only counted if the number of goals were equal. Eventually point values were allocated, and in due course achieved their modern values with a try worth more than a goal. Incidentally, originally 'field goals' could be scored by fly-hacking a loose ball, though this is long gone..
