Right Religion? Which?

as u are saying that every one is saying that his religion is best so i would say that my religion islam is the best. now answering ur ask"that every one is saying that the religion they r following is right religion and if u don't follow them you will perish"actually this is due to our lack of knowledge about religions.the very basic thing which is present in every religion in hidden way or in open way that there is ONE GOD ONLY who should b worshipped. talking about y am i saying that islam is the best religion.first let us see the detail of prophets each religion follow.every prophet was the messenger of GOD and was sent to give the messege of GOD to a particular nation(sorry my english is not that good so if i'm not using proper word pardon me)and every messenger told his follower to believe in the old messenger and just added more in the messege of the last messenger before him.now as muslim we believe that MOHAMMAD(PBUH)was the last messenger of GOD spreading GOD's messege.so the chain of prophethood ends on MOHAMMAD(PBUH).one may understand it as chiristianity was the newer version of jewishism and islam is the newer or latest or final version of GOD's messege.so its just like that u adopt the latest in ur life so y not in case of religion. THE major problem with this ERA or the problem making our generations confuse is"ALL THE RELIGIONS ARE NOT IN THE SHAPE THEY WERE STARTED"the basic messeges and all the basic material which should b the base of believes of any religious follower has been changed and it is changed by the leaders of that religion(imams of islam,POPs of christianity and pandits of hiduism etc.)have changed these basic thing just for thier own benifits.and it hasn't happened now.it has happened a few hundred years back.so the effect now is that OUR LEADERS OF RELIGION at this time also are not aware of it because the teachers of those wherenot aware of the key knowledge.That caused the problems like islam has an image of fundamentalists religion.christianity lost its original shape.and so on problems resulting in we r confused that where to go now. the other thing happened is that religion which is the primary thing has become secondary thing in out life. these are my opinions about what u asked
