While this seems like a minor point, anyone familiar with Jewish customs in the first century can appreciate it. Women were not viewed as reliable witnesses during the time of Christ and would never have been part of a fabricated story. In fact, had the story been contrived, it would have likely been some high ranking Jewish official that spotted the empty tomb and first saw Jesus. This would have provided superior credibility. Instead the story goes like this,

"And the angel answered and said to the women, 'Do not be afraid; for I know that you are looking for Jesus who has been crucified. He is not here, for He has risen, just as He said. Come, see the place where He was lying. And go quickly and tell His disciples that He has risen from the dead; and behold, He is going before you into Galilee, there you will see Him; behold, I have told you.' And they departed quickly from the tomb with fear and great joy and ran to report it to His disciples. And behold, Jesus met them and greeted them. And they came up and took hold of His feet and worshipped Him." (Matthew 28:5-9)
