Proof
You’ve actually highlighted the problem yourself. You say if the Greek gods appeared with their powers, that would be “proof enough.” But then you admit even that could just be called a “test of faith.” That shows the issue: any evidence, no matter how clear, can be reinterpreted to preserve belief. If Zeus shows up, it’s a deception. If God never shows up again, that’s a test. Both outcomes confirm faith. That makes Christianity unfalsifiable, set up so nothing can ever count against it. And when a belief system is built so every possible outcome proves it right, it’s on the same footing as every other religion that makes contradictory claims with the same logic.
Archaeology
You’re right that archaeology can’t “prove nonexistence.” But it can weigh biblical claims against history. When no evidence is found for supposed nation-shaping events, like hundreds of thousands of Israelites wandering the desert or a global flood, the silence itself is significant. If scripture says something happened in real history, but history shows no sign of it, the gap is filled by faith, not evidence. That’s why “we already have the evidence” is important, your evidence is testimony and conviction but skeptics point out that every competing religion offers the same thing. If faith and scripture are allowed to count as “evidence,” then every faith wins at once. That’s not open inquiry, it’s rule shifting so nothing can ever count against the claim.
Former Believers
When someone stays in the faith, it’s credited to God’s truth. When someone leaves, it’s blamed on their weakness or failure. That’s a rigged standard, it makes Christianity “true” no matter what the outcome is. But people who leave give other reasons: contradictions in scripture, unanswered prayers, moral concerns about what the Bible teaches. To dismiss that away as “lack of fortitude” avoids engaging their actual reasons. If every outcome always confirms Christianity, then the belief is insulated from challenge and that’s not how truth should work.
Judas and Open-Mindedness
Appealing to Judas or others who saw miracles but disbelieved doesn’t strengthen your case it weakens it. If even alleged eyewitnesses weren’t convinced, it shows the evidence wasn’t overwhelming and human testimony is unreliable. Christianity today depends entirely on that testimony, written down decades later by unknown authors. If people closest to the events doubted or rejected what they supposedly saw firsthand, how much weaker is the claim 2,000 years later? Calling that “hardness of heart” is an excuse. It really shows the evidence wasn’t strong enough to compel belief.
You say some Christians are open-minded. But open-mindedness means being willing to revise beliefs if evidence demands it. When many here say “nothing could change my mind,” that’s not open-mindedness. Skeptics can list clear examples of what would convince them: a present-day, verifiable miracle or consistent, unambiguous evidence that couldn’t be explained naturally. That difference is telling. It’s not that skeptics demand something silly, it’s that believers often refuse to define any standard by which their faith could be falsified. And if no standard exists, then the faith isn’t held because of evidence, but in spite of it
