This is asked here fairly frequently, so we have an FAQ section devoted to it.

The tl;dr: is that yes, it's generally accepted among historians that a historical Jesus existed; this does not imply belief in miracles, his divinity, etc.

The three questions in the FAQ all give pretty good answers:

• Is Tacitus the main reason historians accept Jesus's historicity?

• How much evidence is there for a historical jesus christ besides the bible?

• What's the best evidence that Jesus did or did not historically exist?

Because those are archived posts, if you have follow-up questions, you can ask them here and tag the user you want to ask like so: "hey u/jschooltiger, can you tell me more about ..." You can tag three users per comment.
