Christians, could any possible evidence convert you to a different revelation-based religion?

Could any possible evidence convert you to a different revelation-based religion, like Zoroastrianism or Sikhism? Could any possible evidence convert you to atheism? (E.g., can you imagine compelling archaeological evidence that all the relevant revelation-based religions were false or fraudulent?) If yes to either, what is the minimum evidence required? If no to both, do you admit that your belief in god(s) unfalsifiable?
