If Germany are successful, it will be fourth time they have won the famous trophy - but it will be the only occasion they have triumphed on South American soil.
Indeed, no European nation has won the tournament on this continent in four attempts.
Czechoslovakia and Holland reached the final in 1962 and 1978 respectively, but Loew hopes his team can go one better in Brazil this weekend.
"In the past we never had this, so we know we can write history," the Germany coach told a press conference on the eve of the final.
"Latin Americans, on this continent, have dominated all the time. So why can we not be the first?
"This could be considered an additional joy for us if we were to win as Europeans on Latin American soil."
The ruthless way in which Germany ripped Brazil apart in the semi-finals sent shockwaves through world football.
If the Germans win again to lift the World Cup on Sunday, Loew is convinced it will not be the last time his players do so.
With an average age of 26, this Germany squad is the sixth youngest in Brazil. And two of their rising stars - Ilkay Gundogan and Marco Reus - are both missing through injury.
Loew thinks the potential is there for Germany to dominate world football - just as Spain did when they won three successive major trophies, starting with Euro 2008.
"We have players right now who are playing at their peak, but we have young players also in the squad and others who aren't even here," Loew added.
"We have players with a fantastic future: Gundogan, Reus, (Mesut) Ozil, Schuerrle, Mueller... they can go on to play for a number of years.
"We can play on top of the world for a good few years yet, with some young players coming in to reinforce the team."
Ever since Germany hammered Portugal 4-0 in the group stages, they seemed destined to make Sunday's final.
Their only scare came in the second round when they needed extra-time to beat Algeria, one of the surprise packages of the tournament.
As a result, Loew is full of confidence ahead of the biggest fixture in his managerial career.
"We don't have any fear whatsoever," the Germany coach said.
Loew's optimism is also born out of the fact that he has done everything possible to get his team ready for Sunday's game - both physically and mentally.
The Germany coach and his backroom staff scoured the planet on scouting missions well before the tournament began and they have been working on a plan to defeat the Argentinians ever since they swept Brazil aside in Belo Horizonte.
"Over the last few years we've travelled and watched international football, in Europe and South America, and we've tried to learn little things that can influence matches," Loew said.
"We've taken on the new-fangled things that are being done. We have looked at Spain and we've looked across the border at what the Dutch are doing - how they train individual players."
That planning extends to penalty preparation too.
Manuel Neuer has been tirelessly studying Argentina's penalty takers so he is primed and ready should they match go beyond extra-time.
Germany have one of the best penalty records in history, but Loew hopes his team win in normal time.
"We hope and expect to decide the match before," he said.
"Penalty shoot-outs depend on so many things.
"They're an additional pressure. But all the goalkeepers are ready for that potential.
"We have tried to analyse the situation."
