We may disagree, but just as @MagdalenaRita said, someone or something has always been there. That is something we have to agree upon. I truly believe that is God, and that God has always existed. You may have some other way to explain it in, but you have to believe that something have always existed, and you mights as well call that something for God.
Atheism requires a lot more faith to believe in. It´s illogical. How could any human being be completely different if it wasn´t for the fact that there is a God? How could every single snowflake be different if it wasn´t for God? How do you and I manage to speak to each other from opposite parts of the world, even in different timezones if it wasn´t for the fact that God let it happen?
