Why don't people just make up their own religion?

Napoleon you don't know half the shit I've had with her. 7th grade she caught onto me being atheist so every time i would turned my paper in, i would get my mid-term and it would show up i never turned it in? So after dealing with this at the end of the year i had to get my parents to come talk to her and she stopped. Literally the teachers up at my school are all pricks except my reading teacher. We had to get pictures taken and I was sitting in math doing nothing and my social studies teacher was the one that was taking pictures and for some odd reason they started questioning me saying "why were you sitting their doing nothing?" so i just sat there and didn't say a word. But this year (my 8th grade year) she stopped doing it after my mom had to talk to her, she actually took my papers. And all my friends would watch me take my paper up to her and we would make a joke about it never being turned in, and one time we were joking about it so the next day i went up to see my grade and she says "you didn't turn it in". And she does try to promote christianity with all of her crosses but its perfectly legal because it's "social studies". We were having a class discussion on our basic rights and it had to deal with separation of church and state, well this guys son they made him preach about god by singing hymns, well the father didn't like it took him to court and we had to choose who actually won the case. Our teacher asked us if we were in favor of the school than raise your hand, everybody in class other than me raised their hand. So next she wanted people in favor of the dad to raise their hand, i did. So after i raise my hand i hear this redneck yell out "he's atheist his opinion doesn't matter!" and all the social studies teacher does is say "connor". If it was me I would be in so much fucking trouble if i said that about christianity. I fucking hate religion.
