ELI5: How did the Israel, Palestine & Gaza Strip situation actually come about and develop?

Apologies if this is and should be obvious to many already. However, I follow the contemporary news cycles on this important and controversial Middle Eastern situation, but I often feel that reports on it assume that all viewers/readers already have an in depth prior knowledge of all that has come before, and how this conflict actually began.
Therefore I thought I'd ask for an ELI5 summary as I'm not sure myself how all of this started. Thanks a lot!

You need to go back hundreds, if not thousands of years, really. But the ELI5 version is that you have two Peoples living in a very small area that really, really don't like each other. Both think that land is their Birthright, and they're carrying over generations of hatred. There's a huge circle of violence going on, to the point where why it actually started *doesn't matter anymore*. 

At this point there's no Right or Wrong side. Both sides are responsible for pretty bad stuff, and both sides seem unwilling and/or incapable of stopping the cycle (though there are doubtless people on both sides who want to!)

If you want an ELI15 explanation, let me know.
