seeing that God is omniscient & omnipotent, what He chose to do is the only possible thing He could do: that which is perfect.
When I say echo of life I'm talking more scientifically, since carbon is the basis for life as we know it, and carbon is the atomic number 6 on the periodic table, due to having 6 protons and electrons per atom.
So when God told a more primitive man He created in 6 days all things, and created man on the 6 day, He's just giving us the echo of life from any perspective, then and now, and telling us we are created beings.
