One of the factors to consider when testing facts, particularly religious claims, is falsifiability. To falsify a worldview or religion, in this case Christianity, you could examine the historical claims of Christianity to see if they hold true. If the claims do not hold true, then that worldview can be eliminated as a viable option to describe reality.
The claims of Christianity not only hold up to the test of scrutiny, they are the only worldview that can. Compared to other faiths, no other worldview comes close to being as testable nor carry the explanatory power of Christianity.

Christianity, the World’s Most Falsifiable Religion
This belief has been a source of contention with many people, even Christians, in the past. But the more I research, the more I find it to be the case that Christianity is the only viable worldview that is historically defensible.
