I'm 13 years old, and I have never felt so much hate for humanity, why are we this way?

I'm not gonna lie, this may be a really dumb post, I'm 13 years old, and I have never felt so much hate for humanity, I'm just watching the news about the situation in Israel. I don't know much about this, but I looked it up, and this has been going on since 1948, thousands of people have died already, and it's still going. Why can't we just fuckin stop this? All of these people had families, loved ones, friends, why are we doing this? I looked up the comments of that video, and then I saw "let's kill every Palestinian" "let's kill every Israeli", can't we just stop this? Why are we like this? Why are we killing each other so much? Everytime I look at the news I see about war, and how humans are killing each other, I can't believe we are this shitty, can't we just live in peace? I don't know what to think, I just feel so much hate for humanity at this moment.<br><br>Edit: I'm going to read all the comments, thank you all for answering.
