Falsifying Christianity

What would suffice to disprove Christianity? I can think of two things off the top of my head:

1.The disappearance of the Jewish people would disprove both God’s promise to Abraham and the Book of Revelation.

2.The discovery of Jesus Christ’s crucified skeleton would disprove the Resurrection.

Anyone got any more ideas? And what would falsify other religions, such as Hinduism or the Ba’hai faith?
