It is overly simplistic but let us examine the electric clock. By its very nature, it requires electricity to function. The electricity can be supplied by at least three sources: a battery, an electric cord from a wall outlet or a solar cell. Without that unseen electricity, it is merely an assortment of mechanical parts that perform no function
it does not "act" as intended by its designer.
If the electrical energy comes from a battery, the clock can perform its duties only until the battery runs down. If the energy comes from the wall outlet, the clock will run as long as the utility company provides power to the outlet. If the energy comes from a solar cell, the clock will function only while light (e.g., the sun) is striking the element in the cell. It doesnt matter where the clock gets the electrical power
but it must have that energy to really be a clock!
On a grander scale, let us apply that condition to a much more complex item we call "human." What do we know about a human? Human does exist
human IS. Let us be so brash as to say that how human came to be (or who "designed" human) is not important for this discussion. We simply know that human IS and that human requires certain things to function as designed
to be an active human. Human requires a livable environment with food, water and oxygen. If any of those elements are missing, the human ceases to function as a human. But there is more!
What happens if all those requirements are present in abundance but the human ceases to function? Why not just patch the holes, replace the blood, install a new mechanical blood pump, inject air and nourishment (replace the battery) and cause that human to continue to function as a human? Some unseen and irreplaceable item is no longer there! The departure of that essential ingredient has rendered the human body to be a inert physical object that had been a human temple.
What is that unseen and irreplaceable item? It is the Soul, of course. Darwins Theory may explain how a human body is generated and how it may have changed over time
but he neglected to explain what gave it LIFE
and when that life took command and how it departed. If we were to research back to the very first cell, the very first atom, we would still have the question: "Where did IT come from?" Sorry, Darwin, you have a lot of facts but you missed the boat!
