It's the old motte-and-bailey argument; the author stands in the bailey and asserts "there is a living God, who created you and cares for you individually, and I have detailed information about this God's nature."<p>When you ask to see some evidence for that, the author runs back into the motte, and says "obviously something led to the existence of the universe, and all my information about the nature of that Something is subjective, which you can't impeach. Since you can't prove my subjective assertions wrong, I'll continue to claim I'm right. If you don't accept my claim you're being unreasonable."
Another example of the very clichéd "atheism is a religion!" trope. I would suggest that when trying to post Christian propaganda to HN, you not use a site which on its home page features "The War on Christian America" and an article defending convicted child rapist Cardinal George Pell.
