Village Atheists are famous for saying "There is no proof for the existence of God." They'll even go so far as to say "There is no evidence of the existence of any gods."
Both of these statements are Bare Assertion fallacies which Atheists feel no need to defend because they claim that non-belief is the "default position." The fact is, from a logical standpoint, a lack of evidence doesn't disprove anything.
In the meantime, while believers are honest enough to admit they don't have absolute proof of God's existence beyond their own experience, there is a growing amount of evidence that shows biblical events are also historical. Since the Bible is the Christian's source book of knowledge about the faith, verifying its events lends more credibility about its understanding of God.
This year, a documentary was released, titled "Patterns Of Evidence" The Exodus." The film was 10 years in the making and challenges the 60 year old consensus that archaeology proves the Exodus didn't happen. By looking at the same archaeology, plus newer discoveries, a different conclusion can be reached.
Once again, the claim of "no evidence" isn't always the end-all, and Atheists need to get over the notion that Christians are ignorant and cling onto a groundless faith. The more we discover and learn, the more we can be assured that our faith does have outside support.
