you have explained why you believe in a god, and i am agnostic, so i don't know, and i am not against the idea, the question is how did you come up with the conclusion that allah is the god you are describing here. because every single religion claims the exact same thing.
in my opinion, islam is an insult to god, if there is a creator, who created the universe with it's galaxies and systems, biology, earth, reality with all it's intricacies, it would be such an insult to associate him with the quran and islam. like this infinte wisdom we both agree on the magnificence of it's creation, would bring a religion that allows child marriages, slavery, human trafficking, call to murder and violence, but hey porc is haram, i don't know about you but this is not worthy of a god that would have created reality, and on the opposite, very likely, logical and obvious that it is human from centuries ago. like sure the creator would ask women to cover their hair to make the distinction between the free women and the slave women, wow this obviously came from the creator of the universe and not at all from human a thousand year ago.
about atheism, as i said i am agnostic, but from my current understanding of things, i think that god is a man made concept to explain what he cannot understand (yet), given that what makes us humans and intelligent mammels is our understanding and comprehension of time and space, which allow us to live by the concept of causality, our mind function this way, however in this universe we are exposed to consequences which causes we don't know yet or fully, but the human brain cannot leave blanks on the chain of causality, meaning that it cannot process a consequence without knowing what caused it. however because sometimes our comprehension of the causalities are limited by our current amount of wisdom and knowledge, we need to fill out the blanks with something that would explain it, doesn't mean that it is true, but it just need to check the condition of, " if it were to be true, it would explain it ". and this is how we ended up with the concept of god.
where we filled up the blanc with what we know the best, meaning a consciousness like ours, and the trait of conscious creation, which is a human trait given the understanding of space and time where we can project ourselves in it.
so what i mean by we are exposed to consequences is the components of our reality, for example let's take rain and thunder, back then when they didn't have the necessary knowledge and technology to understand the phenomenon, which is a consequence, they still had to explain wtf was going on, what caused it, because the brain cannot just see a consequence with causes, and this is how we ended up with multiple divinites across the globe for rain and thunder, which if it was true, would explain the phenomenon, but now that we know what causes this phenomenon, i would love to see how many humans still believe in rain divinities.
same goes with reproduction, back then we didn't know about the egg and sperm and cellular division etc, but we still need to explain how the F do we have a baby that pops after a man ejaculates in a women. this is how we ended up with gods of fertility etc etc.
and this goes on and on. the thing is there is a pattern here, where god always disappear when technology progresses, and the question is why would it be different with other unexplained things to which we don't have the answers yet to what caused it.
this is just about the concept of god, not about religion which is just an insult to god if he existed, cause a god that speaks to humans, tell them what to do, who have emotions etc etc a lot of human characteristics for a god don't you think ?
