All the Gospels mention the fact that women were the first people to see Jesus alive. This is a proof that the resurrection was real. In that culture the witness of women was not regarded very highly. [1] Thus, if the evangelists fabricated the resurrection, they certainly would not have written that women witnessed it first.

"The crowning events of the resurrection narrative are the appearances of the risen Jesus first to the women and then to his disciples, i.e, the eleven. The empty tomb, for all of its impressiveness and importance, is not sufficient evidence in itself for the resurrection of Jesus. What alone can be decisive is reliable eyewitness testimony that Jesus had been raised from the dead." [2][source]
