Hello there! So you want to know about the existence of Jesus, right? Well, let me explain it to you in a way that you can understand.
Now, imagine you have a friend named John. John is a real person, right? You know him, and you see him, you talk to him, and you have memories with him. Well, Jesus is like John, but a long time ago. Some people say he lived 2000 years ago.
Just like you have a birth certificate or an ID, people from back then didn't have those things. But, there are writings and stories about Jesus from a long time ago. People wrote about him and talked about him, and those stories have been passed down for generations.
Now, some people believe Jesus was a real person, and others believe he was a made-up character. But, just like with John, there are many people who believe Jesus really existed and did amazing things.
So, to sum it up, Jesus is like a person from a long time ago that people wrote about and talked about. Some people believe he was a real person, and others don't. It's up to you to decide what you believe!
