I dont know who you are?whether real or fake!!.You are free to choose your religion and dont black mail that you will continue being a Muslim.This is 1.5 billion club. From your saying - major religions of the world were established when Islam didnt even exist-It is very clearn you have zero knowldge in islam. A small kid in any Muslim village will tell you Muhammed was just the last prohet of Islam and Islam acceppts Jesus ,Moses and many oher prophets of GOD. The first man Adam is a Prophet himself-so dont fool around and expose your ignorance!!
