God vs scientist

God was sitting in heaven one day when a scientist said to Him,
"God, we don't need you anymore. Science has finally figured
out a way to create life out of nothing - in other words, we can now do what
you did in the beginning."

"Oh, is that so? Tell Me..." replies God.

"Well," says the scientist, "we can take dirt and form
it into the likeness of you and breathe life into it, thus creating man."

"Well, that's very interesting...show Me."

So the scientist bends down to the earth and starts to
mold the soil into the shape of a man.

"No, no, no..." interrupts God, "Get your own dirt."
