An alternate explanation is not a refutation.

If the unborn is a human person, no justification for abortion is adequate.

In the Christian Story, mind and matter - invisible things and visible things - are both real. The Christian view is not the only way of viewing the world, of course. It has competition.

Our reasons for believing Jesus existed and also that He was who He claimed to be - the God who came down - are the same reasons for believing any fact of history: the documentation is substantial and it passes all the tests of historical reliability. Scholars - both liberal and conservative - overwhelming agree that Jesus of Nazareth was a man of history and the Gospels, on the main, tell His story accurately.

Some say Christianity is just a crutch. But let's turn the question on its edge for a moment. Is atheism an emotional crutch, wishful thinking? The ax cuts both ways. Perhaps atheists are rejecting God because they've had a bad relationship with their father. Instead of inventing God, have atheists invented non-God? Have they invented atheism to escape some of the frightening implications of God's existence? Think about it.

Cursed is everyone who hangs on a tree.

If the Christian doesn't get reality right, he loses effectiveness in this life. If the non-Christian doesn't get reality right, he loses much in this life, and everything and the next one. As Jesus put it, "What does it profit a man if he gains the whole world and loses his soul?"
