Hey :)
I also don't believe in god, i dont't want to order myself into the Atheism part, that's the reason i say I just don't believe in god.
There is much more behind the idea of god than just believing. I wrote a little piece of text about my thoughts and my past in this direction, if you are interested you are welcome to read it (https://steemit.com/religion/@kanonymous/the-engineer-as-atheist)
Anyway there is no use in convincing someone to believe in something which doesnt really exist. It is not like science where you can show somebody facts about, why the world works how it does. It's not like you want to explain electricity and magnetism and the correlation between magnetism and current in conductors.... It is something that some people need, so they have a clue about the whole thing which is called "life" or they think they do. Some people need this to be "god" others use "science" instead and other just don't need things like that to live their life. I like this discussion if anyone is interested to bring this to another level, please respond :)
