Fair question, and my answer is this: The moonlanding, astounding accomplishment though it may be, didn't actually affect people's lives that much. If you decided to ignore it, it had no impact on your life.
Oooooohh... Very, very, very debatable. If not flat out wrong.
I would argue that, whether or not you're aware of the moon landing, or even believe it happened (because there's still plenty of conspiracy nuts who insist it never happened), there is pretty much no way you can go through modern life in the Western world without utilising technology developed or inspired by attempts to land on the moon.
Conversely:
But YouTube has had a huge impact on the world. Just take Justin Bieber. Every single time you hear a Justin Bieber song, you feel YoutUbe's impact on your life. Anyone can share vidoes with the rest of the planet now. Sure, there are other video sites where you can do that, but YouTube is almost always the one that people actually use. The moon landing is a cool thing, but YouTube actually managed to change the world.
I could go my entire life without ever looking at Youtube, and aside from some mildly amusing videos about cats, or the occasional sporting highlights I didn't catch on TV... Well, I wouldn't be missing anything.
In all honesty, I'll agree with you - Youtube did change the world, it has changed the way we interact with one another in the developed world (along with Instagram, Facebook, etc, etc, etc). However, if you're honestly trying to argue that the ripples caused by the implications of some dude being able to show the world what he did at the zoo were somehow greater than the implications of some dude actually going from the blue one to the white one...
Well, I honestly don't know what to say to that, it's as patently untrue to me as the idea that 2+2=19.
More on topic:
Rugby League should be far, far more famous and popular than it is. As it stands most people even in the United Kingdom (where it originates) know nothing about this sport, they prefer Rugby Union (a far inferior product for the viewing audience)...
As for the rest of the world: There's a World Cup on right now, and the United States of America are doing far better than expected, yet I'm willing to bet not a single American on this forum knew there was a World Cup on, and that's even if they knew that Rugby League is a thing.
Seriously. I urge everyone who reads this post, and who has even a passing interest in athletic accomplishment (I appreciate this is not everyone on the forum, perhaps not even a majority), go look up this game - It's awesome.
Use Youtube. Which is, apparently, an even bigger thing than the moon landing.
