I've heard about scientific propositions that have been proposed that go against the accepted theories of understanding. The people who proposed them get argued with, jeered, and sometimes excluded from the scientific community to which they belong because of their insistence that their idea is correct.
For instance, Ignaz Semmelweis, who discovered that not washing hands was spreading disease. "Semmelweis was outraged by the indifference of the medical profession and began writing open and increasingly angry letters to prominent European obstetricians, at times denouncing them as irresponsible murderers. His contemporaries, including his wife, believed he was losing his mind, and in 1865 he was committed to an asylum. In an ironic twist of fate, he died there of septicaemia only 14 days later, possibly as the result of being severely beaten by guards. Semmelweis’s practice earned widespread acceptance only years after his death, when Louis Pasteur developed the germ theory of disease, offering a theoretical explanation for Semmelweis’s findings. He is considered a pioneer of antiseptic procedures." (

Even when evidence is presented, people are extremely reluctant to change their positions. Look at the history of science, and how long it took the Copernican theory to take hold, the ongoing skirmish between classical physics and Quantum Mechanics, disagreements about whether gravity or electromagnetic force hold the universe together. Those are just a few examples, and maybe some of them aren't that great, but you get the idea.
As far as Jesus coming back from the dead, it's pretty tough to come up with a reasonable explanation of how thousands of people, who were religious dogmatists, in the city that was the center of their religion, in the same city that 2 months previously Jesus has been crucified, were so thoroughly convinced of his resurrection (and the tomb was verifiable at the time) that they believed. Now, 2,000 years later, when we insist on a photograph or "scientific" proof of the resurrection (whatever THAT would be), of course there are skeptics.
Back then, to be honest, obviously not everyone became a believer. Back to my earlier point: Some people don't want to believe despite evidence. Some people just want to believe what they want to believe. Some are super-gullible, and others are super-skeptical. It's not always a matter of logic and evidence. Sometimes it's a matter of presuppositions, stubbornness, intuitions, and viscera.
