the universe is complex as a (googolplex) x (googolplex) Rubik's Cube. From start to now, things have been getting more complex. When we reach a peak, that's when things will go downhill and there is nothing we can do to stop it, but to survive with little energy until we have no energy and everything disappears forever and ever. The best way you can cope with such a detrimental reality is to believe in a being with higher power, like god to save us from such atrocities the universe has for us in future.
