We as Muslims believe that every child who was born by either a believer or a non-believer is accepted as a Muslim. Until the ages of maturity when a person may differentiate what is right or wrong by himself, he is accepted as Muslim. 

he meaning of this is that every baby is born on the Nature that God created man on, which is monotheism and submission, but his parents change this according to their religions. This is why Muslims don't baptize, coz Muslims believe that Islam is the religion of nature, this must not carry any kind of insult to non-Muslims. 

Yes Islam is not just a religion, it is a way of life that mentioned every small detail in human life and offered the best way to practice it, from the individual basis till the national basis, and from religious practice till economy and politics. You can hardly find an issue -no matter how tiny or big it is- not mentioned in Islam, this is why Islam is universal. 
During years of strong Islamic nation, science and literature were developing so fast, while other nations suffered from poverty and ignorance, there are big lists of Muslim scientists who changed the fate of humanity, and opened new sciences, in almost all aspects of life, like Ibn Sina. Gaber Ibn Hayyan, Ibn el Haitham, Ibn el NAfis, Ibn Majid,…and so on
