Why were religions and philosophies developed and what use are they?

For some reason people have the need to understand and explain everything, so when attempting to understand and explain things, especially in times where virtually nothing was understood at a scientific level, people would often make up crap that seemed to fit the situation and add in a splash of creativity. eventually they actually believed it. Philosophy is similar, it is when you analyze something and try to understand it and think of it in different perspectives. Philosophies were created for the purpose of bettering others, but religion, though is perceived as a similar tool, is actually a devise that long ago douchbags came up with to take power over, enslave, and torture as many people as possible. Religion doesn't really do anything but give justification to virtually any action whether it be fair or not. Philosophy is a class where amoral college kids go to try and feel better about themselves. These things are perfect for borderline sociopaths and power hungry, war mongering a-holes.
