What actually makes humans different from animals?

And so the question that he posed was, how is man different than the animals? And this particular professor was an atheist, and I knew him quite well. He was a wonderful guy. And he started questioning the class. People say, well, there's communication. And then what do you do? You're like, animals communicate. Well, we have love. Well, animals have love. We have relationship. Animals have relationship. Right? So he's knocking out all of the popular response that people are posing at him. And so I, and obviously this is not a fair fight, right? So I raise my hand and I'm like, people worship God. Now, we as Christians believe the animals worship God also. But he had no answer for that, right? Because that was objectively true. He could not argue that in observation man is, as C.S. Lewis once said, hopelessly religious. Even when people try to get away from religion, they still fall into it, because lives are still full of moral decisions.
