A scientist approaches God and says to Him: "God, we don't need You anymore. Science has finally figured out a way to create life out of nothing. We can now do what You did in the beginning."
"Oh, is that so?" replies God.
"Yes," says the scientist, "We can take dirt and form it into a human likeness, and breath life into it, thus, creating man."
"Well, that's very interesting," God said. "Show Me."
So the scientist reaches down, grabs a handful of dirt, and starts to mold the soil into the shape of a man.
"No, no," interrupts God, "Get your own dirt!"
