From experience, it seems some people want god (a creator) to exist because they don't understand the purpose of life. Therefore, many people believe in God because they don't know what to do with their life. However, we should all understand that it is impossible to prove the existence of god. What people call proof is really evidence; and evidence is essentially subjective interpretations or opinion. From all I have seen though, there isn't any convincing or strong evidence to support that god exists. People, read books like the Quran and the bible and say it is proof that god exists. Well, I read Naruto manga most wednesdays. Does Naruto really exist? People, ignore the fact that books like the bible have been edited by men and many books removed. These texts are filled with errors, contradictions etc.
Hence, I would consider myself agnostic because I accept that it is impossible to prove the existence or non-existence of god. The question of whether or not god exists is similar to asking: "Is there an invisible, intangible, giant cyclops hovering above my head?" This is impossible for me to prove but equally impossible for me to disprove. But are we going to sit all day wondering whether a giant, intangible, invisible cyclops is hovering over my head? No need to worry about something you have no evidence of.
