Nature seems as uncaring as it is unyielding.

The conclusion is in the mind of the beholder, and it is outside of the realm of scientific theory and prediction.

But no such unambiguous signs have been uncovered among the millions and millions of pieces of data we have gleaned about the natural world over centuries of exploration. And this is precisely why a scientist can conclude that it is very unlikely that there is any divine purpose. If a creator had such a purpose, she could choose to demonstrate it a little more clearly to the inhabitants of her creation.

Absence of evidence is not evidence of absence.

The Universe how it came about?

Great mystery.
