During a beach trip one day, me and my brother found this dragon made out of rocks. We were the only people around at the time. There was no designer in sight. Now, Evolutionists, I dare you to convince me that no one built this dragon.
Obviously, you're not even going to try. If you did, props for consistency, but at that point, you've moved away from rational arguments to stretching reality in order to defend an obviously wrong conclusion.
Now, scientifically speaking, nothing can prove this dragon was made by a person. There's even less you can do to determine which person. You can study the rocks, but there's next to nothing you can do to show how they got there. But common sense alone tells us that this dragon is not the result of random processes. In much the same way, we can study the universe, but that can't tell us huge amounts about how it got here. But common sense tells us it wasn't an accident. There is an intelligence behind the universe, and denying that is just plain daft.
Thankfully, the Creator was not as apathetic towards His creation as the makers of this dragon were to their art. He didn't just make us, then walk away. Rather, He had an eternal purpose in mind. The problem is, we're not especially compliant with it. Each of us has rebelled against Him. Almost as if these stones had decided "no, we don't want to be a dragon, we want to be stick men". What happens when an artist is not pleased with his art? It goes unfinished, and gets destroyed. Likewise, when we, who are designed to bear the image of God, instead proceed to bear the image of Satan, we earn for ourselves eternal doom.
Yet this isn't what He wants. He's rather determined to finish His art. The solution? Substitution. If a truly innocent man volunteers to take the punishment owed to the guilty, the guilty go free. But such a man never existed. So God had to do it Himself. He sent Jesus, His Son, to be born of a virgin, live a perfect human life, and die on a cross. There, Jesus bore the full weight of sin, allowing anyone who believes in Him to be forgiven. After that, He rose from the dead. Confessing Jesus as Lord and believing He rose allows us to rise with Him into eternal life.
