Do The Resurrection Accounts Conflict?

Are the New Testament documents reliable? Who wrote them? And when? Do the Gospel writers contradict each other in describing the different places Jesus appeared to His disciples after the Resurrection? Do they contradict one another in other areas? How many women first came to the tomb on Easter morning? How many angels appeared at the tomb? One as Matthew states or two as Luke & John recorded? Do Mark & Luke conflict in their reports about the disciples on the road to Emmaus? Did the Resurrection appearances of Christ really happen or were they only hallucinations? What compelling evidence exists that proves the Resurrection of Christ actually happened? Is this evidence sufficient to convince skeptics & those trained in law?
