Jesus
Do you believe in Jesus Christ? That is a totally different matter altogether and likely depends on the religion that you follow. Some historians think that he did exist, but others think that he was just a folkloric figure. Some folks refuse to believe in his existence, thanks to how vague the New Testament is. On top of that, there was no eyewitness account or other secular evidence of him either.
King Solomon
In reality, there is not a lot of evidence that dates back to King Solomon’s time. It is perfectly understandable why a lot of people are skeptical of his existence. During his lifetime, he was dubbed the richest person in the world. If that was true, it is hard to believe that no one has found anything of his.
