The 2018 Winter Olympics officially kicked off Friday night in PyeongChang, South Korea. The opening ceremony was filled with excitement as athletes from different countries piled into the stadium, eager to represent their home nations. The Olympics is all about promoting unity and harmony between the different countries represented, while also competing against one another in a numerous amount of unique sports. While the games aren't close to being over yet, there have already been some heartwarming and memorable moments from this year's competition.

The debut of Nigeria's first women's bobsled team.

History is being made at this Olympics, as the first women's bobsled team from Africa qualified to compete in this year's games. This is the first time that Nigeria has been represented in the Winter Olympics. The three women competing are showing that you don't need to come from a wintry or frigid area in order to make a mark on this year's games.

The return of Tonga's shirtless, oiled-up flag bearer.

You may remember him from the opening ceremony of the 2016 Olympic games when he came out in little clothing holding up the flag for Tonga. The next day, he was making headlines and gaining a respectable amount of admirers. He competed in Rio two years ago, qualifying to be part of the taekwondo competition. This year, only having experienced snow for a few weeks of his life, he qualified to represent his country as a cross-country skier. You could say his fans were extremely excited to see he was back.

Red Gerard: The 17-year-old snowboarder who won the United States their first medal.

Not only did he win the United States the first medal of the games, but he won the gold medal in his first Olympic event ever. It was a gold medal upset, as Gerard moved all the way up to first place from 11th after an amazing final run in the slopestyle competition. It's safe to say that he could be America's new snowboarding hero (sorry, Shaun White).

America's favorite figure skating pair: Alexa and Chris Knierim.

These two have gone through a lot in the past two years. Alexa was struggling with a rare gastrointestinal illness that forced her to have three different surgeries, and it dropped her to a weight of 80 pounds. However, this wasn't going to hold the two of them back, as they bounced back and were able to compete in this year's games. They have overcome huge obstacles to be able to compete at these Olympics, and they have put on the best performances that they possibly can.

Chris Mazdzer picks up a silver medal in the men's luge competition.

While it's a huge accomplishment that Mazdzer to even be accepting a medal on the podium, he also contributed to making more history for the United States. This is the first medal that America has ever won in the men's singles luge competition. This is his third Olympic games he's been in, and the other two times he competed, he came in 13th place in the same competition.

Mirai Nadgasu: The first U.S. woman to land a triple axel at the Olympics.

We've all watched figure skating at the Olympics and wondered how they do it, but this performance was on a whole new level. Landing a triple Axel perfectly is something that every Olympic figure skater dreams of accomplishing. Because a triple Axel is such a difficult move to master, it's unpredictable whether or not even the best could land it at the Olympics. Because of her almost perfect performance, she helped lead the American figure skating team to a bronze medal.

Mark McMorris wins a medal for Canada just 11 months after having 17 broken bones.

The 24-year-old snowboarder from Canada won a bronze medal in the men's slopestyle competition. Just last year, he was suffering life-threatening injuries after mistiming a jump and hitting a tree while still in the air. It was uncertain as to whether or not McMorris would even be able to return to compete in this year's Olympics, but he was able to bounce back, and stun the entire world.
