Scott Adams of Dilbert fame asks:

Suppose we found a blob on Mars that moved under its own power and wasn’t a carbon-based life form. How could we tell if it was intelligent?

....What if the blob authored a book?

Don’t answer too quickly because it’s a trick question. Remember, a trillion monkeys with typewriters can write a book if you wait long enough. So let’s up the ante and say that the blob on Mars writes lots of different books. And let’s say it composes some music, designs some evening gowns, and paints some lovely pictures too. Now do you conclude that the blob is intelligent?

It’s a trick question because atheists believe that the Big Bang did all of those things and more. The Big Bang caused the sequence of events that culminated in the Bible, the Koran, and most important – Dilbert comics. If the blob on Mars created literature, we would surely consider it intelligent.
