It is very easy. The main claim of Christianity has been that Jesus rose from the dead. No scholar, group or individual has been able to prove that wrong. It there has been please let me know. Gary Habermas has an excellent book entitled "The Historical Jesus." There is some very good information inside.
Before you can ask other people to prove something wrong, you first have to prove that it's right. And no Christian has ever been able to do that. You've set an awfully high bar for this Gary Habermas, so I went and looked up his Q&A
on "The Historical Jesus". Needless to say, I was less than impressed. For example, he cites letters from Paul (such as 1 Corinthians), who never actually met Jesus, because they were written within a few years of Jesus's supposed death, and he cites "extra-Biblical" writings which date from the mid-first century to about 110 AD. What he does not do is cite from any historical records from the time Jesus supposedly ministered.
He also cites the discredited passage from Josephus by stating that "the vast majority of scholars who address this issue think that although Josephus' longer statement about Jesus in Antiquities 18:3 has been altered a bit, the bulk of it was written by Josephus." This is not believable, not the least of which because it doesn't fit the paragraphs that precede and follow it. He also refers to Antiquities 20:9, "concerning Jesus being the brother of James", but this is also not believable - it could very easily have been referring to another Jesus (indeed, it brought up another Jesus at the very end).
The first person to 'notice' these passages was a Christian bishop named Eusebius, during the 4th century CE. Nobody who discussed Josephus's Antiquities until them even brought them up, so it is extremely likely that they are fraudulent (not to mention the fact that Eusebius was known for committing pious frauds, lies for the purpose of advancing his religious beliefs). Origen, a 2nd century Christian apologist who quoted from Josephus at length, never mentioned either passage.
In addition, Habermas said that of over a thousand recent publications on the subject of the historical Jesus, he was aware of less than five which doubted or questioned that there was actually a historical Jesus. Even I can spot the weasel wording here, not to mention that he doesn't mention where these publications were, well, published.
I don't have time to go through all twenty of the questions that he answered, but it's pretty clear that even if someone else asked them, rather than him phrasing them himself, they intentionally gave him plenty of wiggle room so that he could avoid saying something that was definitely untrue. In other words, I'm not impressed at this apologist "historian" or his book.
I would advise you to read up on the subject, as I pointed out, it is so easy to stand on the sideline and cry myth. By the way, did you know the Apollo Moon landings were faked?
Funny how we have verifiable evidence to show that they actually happened. That is to say, transmissions from the Apollo landers, objects brought back from the moon, etc, etc. I'd say it's been pretty well proven that the moon landings did in fact happen.
