ELI5: How does Wikipedia avoid abuse?

So I understand that Wikipedia has measures in place in case people edit articles inaccurately but a good amount of Wikipedia including some of the more complex topics in science and mathematics for example have very accurate, cited information free of errors. Why did people spend the time to write these articles in the first place? Why, with the way the internet is, are articles not constantly getting debased? It just seems like so many websites, even if they have positives sides have those people looking for a reaction or just trying to cause trouble, in all the time I've used Wikipedia, I've only run into one serious error(page about ostriches replaced with stuff about Nazi Germany) and it was fixed later that same day.

Because the people who administer the site are diligent in their work. Also, logs are taken every time a change is made, so it's not hard for registered editors to see where someone has taken a huge chunk out of a page and replaced it with garbage and then simply undo the changes.

In addition, sensitive topics are often blocked from editing by unregistered users or users who are not given permission by the administrators. This reduces biased defacement of pages like "Nazism," "Israel," and other such hot topics.
