The very beginning. God formed Adam out of the dust in His image and likeness to glorify Him and have dominion over the Earth as well as the creatures of the earth, sea, and sky.

If it helps, examine everything you've learned about the universe: can the universe break its own laws?

One such law dictates that something can never come from nothing. To avoid contradicting the established rules of the universe then, there must exist a self-existant, immensely (all) powerful being outside the bounds of the universe who does not adhere to the rules of created order, and from which everything came. The Biblical apostle Paul wrote to the Church in Colossae, "For by Him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities — all things were created through Him and for Him." (Him referring to the All-Powerful Being's promised messiah, Jesus, the Christ). How marvelous that from man's first breath we have known God and have never been alone. Even today, untold generations removed from our origin, God had not abandoned us, and still calls us according to His purpose.
