Affiliate Marketing Secrets

I am a canadian lebanese guy and i want my official religion on my documents in lebanon to be: atheist or agnostic or even apostate.
I dont mind the label, the point is that I do not believe in god, and I really believe all religions are man-made, and that the idea of god is just a part of human imagination.
If I reject the religion handed down from my parents and all other current options, do i have to renounce my lebanese citizenship?
This is an extremely sensitive issue for me right now because I do NOT accept the need for a sheiks approval in order to get married. I’m 24 and I’m thinking of getting married. I will definitely not be marrying a religious person, and I have absolutely no requirement that the girl be sunni like my parents. That aside, I am proudly not affiliated with any religion, and I’m hoping to find a way for the lebanese government to let me be who i am, and not who my ancestors were.

I just need these two questions that I can’t find anywhere.
DOWN
1. Principle proposed by Darwin that suggests that ALL species- living and extinct- were derived from a common ancestor (2 words)
5. Principle proposed by Darwin that suggests that species look different than their ancestors as they adapt to live in different habitats and establish different niches (3 words)

I ask this because arabic is linked to islam in every way. Arabic has always been part of islam.
eg arab-islamic empire. There is reasonable amount of proof that suggests that arabs who’s ancestors where christians were probably not affiliated with the islamic empire.
So if you are of christian arab descent are you really arab?..
