If Jesus Christ was who He claimed to be, and He did die on a cross at a point of time in history, then, for all history past and all history future it is relevant because that is the very focal point for forgiveness and redemption.
If there were more than one path to salvation then it would totally negate Jesus' sacrifice on the cross, his life, his teachings.
The first thing that stuck in the minds of the disciples was not the empty tomb, but rather the empty grave clothes - undisturbed in form and position.

Christ appeared alive on several occasions after the cataclysmic events of that first Easter.
