I need Help

I made this and clicked submit and it stated there was an error but cant seem to find the problem can someone help. Here it is, I had to take out the < > so it would show up,

titleUnordered Lists /title
body h1 Some random thoughts /h1
li The universe is big. It’s vast and complicated and ridiculous. And sometimes, very rarely, impossible things just happen and we call them miracles /li
li You want weapons? We’re in a library! Books! The best weapons in the world /li
li The way I see it, every life is a pile of good things and bad things. The good things don’t always soften the bad things, but vice versa, the bad things don’t always spoil the good things and make them unimportant /li
li We’re all stories, in the end. Just make it a good one /li

please use markup:

this way you can post html code with <>, also include: error message and exercise url
