Hello @adrianobalan that's good article and you focus on good question which should always altered with different religions.About Hindu region,I give You full detailed How life starts and ends.I think You said right Because in my Hindu religion says There are Four ages(yug)of life
1.Golden age(Satyug),Where people in this age are always happy,there is not any crime,not war.Only peaceful life people get.
2.Silver age(Treta yug),After golden age life comes in Silver age where people get less Happiness than golden.
3.Bronze age(Dwapar yug),This is the age where people start praying with god,people start angerness,Greedyness,Sex thinking and other evil behavior.
4.Iron age(Kal yug),That's the kalyug where We live now.You understand what happened in this Age by observing from outside and From news who always tells mostly about crimes.
According to Hindu religion all people's life repeated in this ages.
