What is the purpose of this life, why do people have kids?

The life can be blessing or pain,full of trials and turbulations.

I still wonder what is the purpose of this life and why do we have kids...

I know most women feel pressured by the society and hense it is transfered over to men...so you become an adult in college or work,are you dating yet? No shit lets get you hooked up,are you engaged yet, when arr you getting engaged,engaged, awwa...how beuatiful is your ring,i am so jealous... when are you getting married,married,aaw. Are you pregnant yet? No,trying? No,waiting? Is everything okay?did you see anyone?
Pregnant, aawa,how is it going? Delivery,are you gonna have a 2nd one, oh when? And it is never ending...
