1. Observe what God created. Is there anything comparable that a human being has made?

In the beginning God created the heavens and the earth. Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. And God said, "Let there be light," and there was light. (Gen 1:1-3, NIV)

2. Observe God's interaction at the level of human beings. Can any human being do this?

So God created mankind in his own image,
in the image of God he created them;
male and female he created them.
God blessed them and said to them, "Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground." (Gen 1:27-28, NIV)

With my great power and outstretched arm I made the earth and its people and the animals that are on it, and I give it to anyone I please. Now I will give all your countries into the hands of my servant Nebuchadnezzar king of Babylon; I will make even the wild animals subject to him. All nations will serve him and his son and his grandson until the time for his land comes; then many nations and great kings will subjugate him. (Jer 27:5-7, NIV)

3. Observe God's judicial view of transgressions against His laws. Are there any human beings who can adjudicate transgressors of God's law?

And he passed in front of Moses, proclaiming, "The Lord, the Lord, the compassionate and gracious God, slow to anger, abounding in love and faithfulness, maintaining love to thousands, and forgiving wickedness, rebellion and sin. Yet he does not leave the guilty unpunished; he punishes the children and their children for the sin of the parents to the third and fourth generation." (Ex 34:6-7, NIV)

No one can redeem the life of another
or give to God a ransom for them
the ransom for a life is costly,
no payment is ever enough (Ps 49:7-8, NIV)

And this is the testimony: God has given us eternal life, and this life is in his Son. Whoever has the Son has life; whoever does not have the Son of God does not have life. (1 John 5:11-12, NIV)
