Religion
I wanna talk about religion for a second. Now, before i say all this understand that i do believe in god and this is not an argument for atheists, just for me. The worst mistake the world ever made was taking the idea that there is a higher being and creating a belief structure around it. If everyone at some point in history would've acknowledged that there is a god and that he created the life that is all around us in some form or another then countless wars and deaths in general would have been avoided. Think about it, I know alot of you are catholic and this is going to make you shun me, but seriously the crusades, the martyrdoms, everything. It all could've been avoided if religions didn't exist, if people would just say we believe there is a higher being or beings and that creation was a result of them. People get so lost in religion that problems occur because of it.
