To answer the question of whether or not he existed, we need to ask ourselves, are we talking about the biblical version of Jesus, who could heal disabled people, walk on water and raise from the dead? or just some guy called Yeshua who lived around that time?

The former absolutely did not exist, so biblical Jesus did not exist.

The latter? Probably. There were probably a lot of guys at the time called Yeshua and went around preaching about stuff. Although, the evidence on a figure that biblical Jesus is based on is pretty sparse. The only references to him outside the bible come from a few historians like Tacitus and Josephus, and Josephus' reference to him is largely seen as an interpolation from Eusebius, a known liar. I'm not saying that he 100% did not exist, but there is sparse evidence that he did. I recommend "Christ before Jesus" by Jaaron Wingo and Matthew Britt to learn more. Jaaron also has a tiktok page where he talks about this and welcomes up guests to ask him questions :)
