Why are we humans religious? Well, that is an easy framework for defining a meaning of life. If that is fine for you then by all means do so. However, it requires a mutual respect. I have a right to question your faith - and I have no obligation to subdue to any kind of taboo, e.g. drawing the Prophet Muhammad etc.
Any human being is more valuable than any form of god (or God, if you prefer so). Life is the most precious thing we have. Live it and stay with it.
