Christianity and Islam share a common creation story because both religions trace their roots to the Abrahamic tradition, which includes the belief in one God as the creator of the universe. The similarities in creation narratives can be attributed to the influence of shared religious texts, such as the Hebrew Bible (Old Testament), on both faiths.
Islam, as with Christianity is a faith. A belief system. Not a form of government
Most common tattoos that are being used to symbolize Islamic faith are Crescent with star and Koranic verses perhaps in Arabic calligraphy. The crescent with star, however, did not start as an Islamic symbol, but rather gained popularity as a nationalist symbol after the creation of Islamic Republics of Pakistan and Turkey, eventually becoming a symbol that symbolizes the religion itself.
Christianity is not against Islam, though it does conflict upon the basis of faith. But from the Islamic perspective Christianity it self gives testimony for the Last prophet of Islam.
Similar to Christianity, a strict interpretation of Islamic holy texts does not support coeducation. Not all of the Islamic faith support a strict interpretation of Islamic text however. It is best to approach this question on a case to case basis. A conservative member of the Islamic faith will most likely oppose coeducation while others might not.
