Frederick Brown wrote a one-page sci-fi story.

To paraphrase, in the far future a linkage was arranged between all the massive supercomputers on all the planets in the universe, to provide enough computing power to deal with the really hard questions.

On the day that the linkup was to go into effect, the Chief Scientist threw the master switch, and then posed the machine the ultimate, up-till-then unanswerable question:

Is there a God?

The machine answered instantly:

"There is now."

The Chief Scientist made a desperate dive for the switch, but a bolt of lightning, from a cloudless sky, killed him, and fused the switch shut.

Brown wrote that in the 1950s.

Be afraid.

Peter.
