Since there are already so many religions in this world, why is it necessary for us to have another religion called Buddhism? Is there any extraordinary characteristic or contribution or significant feature that Buddhism has which other religions do not have?

There is a school of thought, which says that all religions are essentially the same. There are no significant differences. The only difference is in the interpretation and practice. After all, in the final analysis, all of us end in one place, either heaven or hell. That is the common belief of most religions. Does Buddhism share this viewpoint? To answer this question we have to examine what is meant religion.
