The most memorable moments in any sports competition are created by none but the athletes. It is in their blood to shine and create some unforgettable moments for the viewers. Olympics 2016 wasn't any different.

Rio 2016 produced plenty of moments that have been etched in history -- from an Indian woman athlete bagging the first-ever silver medal in the mega quadrennial sporting event to two athletes celebrating a wonderful married life ahead.

We look back at the event, which concluded amid much gusto and euphoria on Sunday, Aug. 21, and selected some of the most memorable moments. Here is the list:

PV Sindhu

The star badminton player from India who achieved three milestones -- becoming the first ever shuttler from India to win a silver medal in the Olympics, the youngest athlete ever to win a medal from the country, and the first woman from the country to bag the silver medal in Olympics.

Check out her achievement.

Sakshi Malik

The woman wrestler from India was not a very known name before the Olympics and not many regarded her as a medal contender. However, if there is one thing sports teaches us, it is: never write off the underdogs. Sakshi, 23, became the first ever woman wrestler from the country to win the medal in the Olympics.

Check out her achievement.

Dipa Karmakar

Dipa's story has been one of the most inspirational stories from the Olympics as a whole and we can't be happier. The short-statured Indian gymnast -- the first-ever woman gymnast from the country to qualify for the Olympics as well as the only gymnast ever from India to make it to the finals of an event at the games -- won billion hearts after her commendable show in the games. 

She didn't win a medal but she did all that which made her an instant hero to many. Check out her achievement.

Usain Bolt

So many times have we mentioned the track and field athlete as one of the greatest ever over the past few years. It is but unfortunate that he took part in his final Olympics. However, as the famous saying goes: careers might end, but legacies don't. 

The Jamaican sprinter bagged the coveted 'triple triple' [three gold medals in three-straight Olympics] and furthered his legacy as one of the greatest and the most iconic athletes of all time. Check out his achievement.

Michael Phelps 

Like Bolt, Phelps too plied his trade in his final Olympics this year and does he go out with a bang. 28 medals (23 gold, 3 silver, 2 bronze) in total from the Olympics, an unimaginable feat. Probably happens once in a generation. The 31-year-old American took home six more medals (five gold and one silver) from Rio 2016.

Check out his achievement.

Simone Biles

The 19-year-old US gymnast is a legend in the making. Right there on top among the greatest already, it can only be left to imagination now what Simone can achieve more over the years. She took home a total of four gold medals and a bronze from Rio 2016 to give a glimpse of her stunning abilities for the first time ever, with the whole world watching.

Dipa Karmakar, who participated in the women's vault finals alongside her, proclaimed that Simone is one of the greatest gymnast she has ever seen and will ever see in the future. A statement like that coming from one of those very few athletes in the world who have perfected the produnova vault, says a lot.

Refugee Olympic Team 

Ten athletes feature the refugee team, the first of its kind seen in the Olympics. The team featured five athletes from South Sudan, two from Syria, two from DR Congo and one from Ethiopia. A grand welcome was bestowed on them on the opening ceremony at the Maracana Stadium and that gave them the much-needed hope. 

The hope transpired very well for 18-year-old Syrian refugee swimmer Yusra Mardini, who made quite a mark in the women's 100m butterfly heats but just missed qualifying for the next round by a whisker. Nevertheless, she made herself a sure medal contender for 2020 Tokyo Olympics.

The marriage proposal 

Two Chinese divers won each other's hearts as well as the hearts of billions watching the event on TV when a marriage proposal was perfectly executed and the best part, the final answer also remained positive. Chinese diver He Zi had just collected her silver medal in the 3m women's springboard final when fellow diver Qin Kai entered the podium presentation and got down on one of his knees. 

Qin Kai then took out a diamond ring and proposed her. She said yes after making him go through a lengthy wait. Little did they realise that they were creating an unforgettable magical moment.
