I love this. I love the fact that even the atheists out there are still not 100% convinced by their own argument.
'Probably', doesn't cut it. They're still not sure are they? They're uncertain in their own faith.
'Probably' incites doubt. Doubt leads to questions, questions lead to answers, answers lead to learning, learning leads to truth.
Without realising it, they've invited people to question God's existence. Maybe people who've never given it a thought before. For that we need to thank them.
