before commenting on religion, first you need to understand what is Hindu, Muslim and christian Hindu is not a religion, it is a 'region/place' where some people are living over there called hindus and name originated form sindhu river, in this case all indians are hindus, people are migrated from differnet place of world to india and to get supreme power in the community they made upper and lower casts. In Islam says, Islam is not a religion, It is an arabic word which means that follwers of submission to god in peace is called islam. Allah is not another god, existence of supreme power is callled god in english, allah in arabic, deyvam in south language. Jesus never called him as Jesus christ during his life time, his original name was Esha then ecome eshos and finally Jesus through latin word. Bible is meaning form the latin/greek word biblos means book.
So first learn yor religion ie baghavadgeetha, ramayan, then go to Quran/bible, finally you will say that religions are cretaed by humans.
As a indian we simply follw others and thinks that we are great and other are fools. So comeout from the box understand the world, wish the best
