Grand designer behind the grand design

The balance of universe depends on so many constants. If it had differed by a hairs breadth a life-permitting universe wouldn't have occurred. Gravity is determined by a gravitational constant. If it had differed by 1 in 10⁶⁰ parts universe would have collapsed. To put it into perspective there are only 10¹⁴ cells in human body. Expansion rate of universe is driven by cosmological constant. If it had changed by 1 in 10¹²⁰ universe would have been life prohibiting. Even distribution of mass and energy in the early universe to which big bang explosion occurred is very very precise. If it have differed by 1 in 10¹⁰¹²³ universe would have been hostile to life. We are not even able to display this number using the current technology.

Complexity of human DNA is far from being understood.Even the human fingers are a mystery. No two human persons have the same fingerprints.
