mmm, it seems this question is popular on italki too. I searched for the word "god", and it found here many similar questions, and some typos like "a want to learn english very god" :)
I am not sure if that person who wrote this question is looking for answer, maybe he is just laughing on every response ;-)
As here are so many religions on the Earth, so I think here is at least one god. It seems that many religions are trying to make people better, and also people have done many unbelievable things only because of their belief (e.g. look at those buildings, sculptures, statues...) I was almost crying (you know, men don't cry :-p ) when there were destroyed sculptures of Budha in Afghanistan (how could someone destroy 1500 years old thing :-/ ), I was almost crying by happiness when man from India was talking about their religion and I really love gypsy's version of Christian religion. When I die and I will find out that there is no god, I will force/make whole universe to create god for each religion, even the Poseidon. If there is only one god, I hope she/he/it will like me after my death although I would like to have the god for every religion, I just don't want to feel that after my death the game is over...
P.S. I have read all these answers (last one by jassi), and it is a pity that asker didn't put his opinion here... But my English is not so good to understand Myung Sung answer, ah I need better dictionary. :) I love you guys (girls and boys) for your sincerity, I am not able to choose my religion or to say directly I believe or I don't. Actually I am working on my own religion, it is called Physics, you know, when you do not understand something but you believe that, I think it is called religion, and there are so many things I do not understand in physics but I have to believe what my teachers said :-D
P.S. if you have read till the end, sorry for such long post.
