I know I am going to look pedantic with technicisms, but nowadays the word "atheist" is overloaded to such an extreme that it is hard to argue about it. The term itself has reached the status of fashion god term.
Take concepts like agile or lean startup. We all can define them properly, but for a large amount of people their meaning boils down to one core idea: "Everything that is beautiful, eternal, the right way, reliable and not evil".
Sadly many people believe the concept of god is binary, either yes or not. In that case one is moving only in one dimension: the Atheist (NO) vs the Theist (YES)
In my opinion most people fall into a third category, the agnostics, whose belief is more in line with: "I never thought it was such an important topic I had to think about and take a hard stance in one side". Obviously these people are extremely hated by those who thought hard to take an stance in their beliefs
Then there are people who do think about God and find flaws in the question. Most people think about God as a super human being, but a Pantheist thinker would claim that God is very much real, just not someone who is self aware, but rather "something", like the universe itself, the laws of physics, Gaia or any other thing
There is also the Pandeist branch. The ones who would claim God "was real" he is the one who built the universe, however that someone sacrificed his own life in the process, so is now non existent
In any case all these arguments are based around the belief that there is one Universe so one must argue if it was created. Ironically people also do argue there is no such thing as Universe or even a Multiverse. Some argue that anything that can be computed will exist, therefore that means that if one can imagine a place where the laws of physics are different as we experience them, it will exist

Coming back to your question: We programmers are the ones who deal daily with the powers of computing. We compute everyday of our lives. One should be more flexible to admit that anything that can be computed will inevitable exist, even the concept of God.
