I'm not sure why there is such a persistent meme about questioning Jesus' existence.
Certainly, not everyone will believe in the things that He did, nor do I expect them to believe it. However, even among some of the most diehard Atheist Historians, to claim that Christ never existed is something that is easily disproved. See: Dr. Bart D. Ehrman (https://www.youtube.com/watch?v=43mDuIN5-ww) Keep in mind, Dr. Ehrman is probably one of the most outspoken Atheists critical of both New and Old Testament theology.
There are Atheist celebrities like Dawkins, Hitchens, or Harris, who get a lot of press and coverage, but as far as "In the weeds" detail-oriented historical and archeological debates on up-to-date understanding of the ancient world? Dr. Ehrman is probably in the top 1-5% of Atheist debaters to look towards.
People are welcome to believe whatever they like, but it's just embarrassing to read people write this sort of thing in the same way it's embarrassing to see people repeat the "We only use 10% of our brain" thing.
