Atheist, grew up in a muslim family. Followed some of the muslim traditions until 10 years ago, when I asked myself "is there any proof (objective and factual) that god exists ?"
The answer being no, I dropped out lol. The Quran is vowed to be hegemonial, and doesn't allow criticism of any kind, claiming numerous "scientifical miracles" to be related in it.
When you check, double check, triple check, you see that's it's all fake propaganda written by bedouins of the arabic peninsula from the 7th century obviously. While it claims otherwise, nothing in it that is written couldn't have been by men.
