Angela's Ashes and how religion is bogus

So I'm watching the movie AA and how this kid goes to confession. 
And the priest tells him that he has to do like 3 Hail Mary's and 3 Lord's Prayer and then he is off the hook or forgiven or whatever. 
It hits me right away at how everything, from thinking that one does something wrong through sin to the penance doled out is all just made up by humans. 
I mean, first of all the kid didn't sin. It's just a bunch of guilt tripping bullshit and then the penance is created to make him feel better. 
Just a bunch of bullshit made up entirely by humans to somehow make themselves feel bad then better all from a book of a bunch of made up stories by other humans. 
Religion is bogus.
