God is sitting in heaven when a scientist prays 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 breath 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."
