Moses is like a computer program that helps people translate languages from one to another. It's kind of like having a friend who knows two languages really well and can help you understand what someone else is saying.
When you want to use Moses, you give it a bunch of sentences in one language, like Spanish, and then tell it what language you want those sentences translated into, like English.
Moses looks through all of the sentences you gave it and tries to figure out the best way to translate them. It uses fancy computer algorithms and rules to help it decide how to translate the words, sentences, and grammar correctly.
Even though Moses is very good at translating, it's not perfect. Sometimes it gets confused and translates things in a weird way. That's why it's important to have people check over the translations to make sure they're right.
Overall, Moses is a really helpful tool that allows people who speak different languages to communicate with each other much more easily.
