The question inherent in all of these challenges to the original story and original cast is this: How could anything like the resurrection be true? The question is not asked with the intention of getting an answer. It is rhetorical, hostile and unbelieving.
So, how does one know it is true? First, not a single witness of that first Easter morning subsequently denied what he (or she) observed. Human nature tells us that when those who publicly stated Jesus rose from the grave were threatened with death unless they recanted, at least one, and probably more, would have said it never happened, if it didn't occur. They would have wanted to live. Not one recanted. All of the Apostles died martyrs deaths, except John, who died in exile.
The second reason is also logical. What kind of loving father would direct his lost children through a bad neighborhood, if he wanted them to get home safely? If no human father would be so cruel, why would God, after giving up His Son to die for humanity, create a flawed road map so they would get lost in their search for Him?
Christians who believe the Bible's account of Easter believe it because they also believe God's spirit guarded human hands from making errors in recording these events. Skeptics have no such guide. They should be humbled that God is far wiser than the wisest man. (1 Corinthians 1:25-27)
Before accepting what heretics and unbelievers say, consideration should be given to what is contained in the guidebook.
