If they were lying, don't you think they would have renounced what they claimed?
All twelve disciples were crucified just like Jesus was.
The rest were executed, burned, or eaten by lions and they all refused to renounced what they witnessed.
At least according to the stories that were finally written down 70 years after the events.
That there's a literary license to kill...
That's like getting to write the story of Martin Luther King Jr. in 2038, knowing that NObody will ever ask you for a link.
