How the "HINDUISM & SIKHISM" philosophy differs from that of JAINISM,BUDHHISM & ATHEISM ?

Jainism and Buddhism do not believe god, but they have certain principals, no non veg., no intoxication and so on. Sikhism is a combination of Hinduism and Islam. Guru Nanak says so in the grandh Sahib. Jains made the Thirthankaras and the Biddhists Buddha as God. Theu are only a branch of Hinduism.
