“Nessie” (the Loch Ness Monster)
From Christian apologist James Bishop’s Blog:
Question 3: Is the God of the Gaps reasoning a valid way of determining the existence of God?
If the atheist has not bailed on you yet, he/she will likely run now. For if he/she answers NO, then it will become clear that nothing can count as evidence for the existence of God. Why? Because if the only “evidence” the atheist “Judge/Jury” will allow in his/her kangaroo court is a Gap (something that cannot be explained by science/natural law), and God-of-the-Gaps reasoning is also not allowed by the atheist, then it is clear the atheist demand for evidence is a sneaky, dishonest game of “heads I win, tails you lose.”
Of course, if the atheist answers YES to question 3, then the theist is free to raise Gaps as evidence for God (origin of Life, origin of the Consciousness, etc.). This is why the atheist will run or change the topic – his/her demand for evidence puts the atheist in the position of having to a) acknowledge the deceitful nature of their demand or b) acknowledge there is evidence because of certain existing gaps.
Answer from Skeptics: Yes, a dramatic miracle would be good evidence for the existence of the Christian god, Yahweh/the resurrected Jesus. Something like this: He appears in the sky simultaneously, to every person on the planet, telling us all, in every language known to mankind, who he is and what he wants. That would be a feat pretty hard to fake. I would bet that most people, including myself, would believe in his existence due to such an event. But I (and I would bet most skeptics) don’t insist on this level of dramatic evidence to believe in the existence of the Christian god. I would be satisfied with the same evidence that it would take for a Christian to believe in the existence of the Loch Ness Monster, the Abominable Snow Man, or Big Foot. No more. No less.
