Reincarnation of a human to be turned to a god

Prologue

My name is Zach in going to tell you how i became a god and my adventures after i turned to a god.

Zach's POV
*Clock rings*
Zach goes out of the bed and goes to the bathroom to take a bath and wears his uniform then goes to the Dining room to eat his breakfast
""Good morning Zach"" (Zach's mom and dad)
"Good morning "
*After he eats and wears his shoes*
"Bye" (Zach)
"Do your best on school okay?" (Zach's mom)
"Okay mom" (Zach)
I went out to go to school my, usual routine but not today.
"Give me all of your money"(??)
"No way!"(??)
I saw a person younger than me getting cornered and looks terrified and a thug looking person holding a knife threatening her into giving all of her money to him and is pissed. Then i ran as fast as i can to try to stop him from stabbing her.
"Huh, what do you wa-"
I was able to punch him the face and he looks a bit hurt. Then he gets even more pissed.
"You f***in brat!"(Thug)
"F***!"(Zach)
Then he tries to stab me luckily i was able to dodge that attack and i punched him again
"Ugh!"(Thug)
but this time i hit him in the torso and he looks even hurt than before. Then he attacks again but i was not able to dodge it and got stabbed
"Gah!"(Zach)
I tried to get the knife out even if it was painful and stabbed him, I was able to hit him in a vital spot and caused him to lose a lot of blood including me but I knew it was the end of me. At least i was able to save a girl from dying.
"Mister!"(Young girl)
The girl runs to me and calls the ambulance.
"You..do not need.. to...do it..im about to... die anyway"(Zach)
"No! the ambulance might be able to get here on time and heal you!"
"Good bye...Young miss"(Zach)
"Mister! no you cant die! not yet please!"(Young girl)
As my vision slowly blurs and darkness consumes me i see the girl crying and at that moment my life was ending.
I can see a bright light around me and as the light disappears I can see an Old person wearing a white robe.
"Is this heaven?"(Zach)
"No you are not"(Old man)
"Then what is this place?"(Zach)
"This the gods realm i called your soul to this realm because you were able to sacrifice your life for a person who has still many years to live for"(Old man)
"So what will happen to me then?"(Zach)
"You will live a new life in another world different from yours"(Old man)
