Allah and his so-called prophet Mohammed are the invention of Satan. Buddha leads people to hell. If so, that's because you have been influenced more by the pluralist idea that you mustn't criticise anyone's religion, than by the bible's clear words. Another reason Christ is unique, is that he gives one hundred percent assurance of salvation. There is a saying that truth is stranger than fiction.
Fiction has that kind of neatness about it that marks it out as fiction.
I can understand how Islam, Buddhism, Hinduism, Taoism, Confucianism, and all the other isms can be the product of human thinking. They all teach what our human nature expects to hear, and reasons is true, namely that our salvation, however that may be conceived, is brought about by our own faith and goodness. In Buddhism you acheive enlightenment by following the eightfold path. In Islam Allah weighs your good deeds and your bad deeds, and however the balance comes out determines your eternal destiny. That God should become human in Jesus, and allow himself to be tortured and executed so that he could save us from the penalty of sin, is just absurd to human wisdom.
