Every person on the planet have right to believe what they want. Either that be God, or they believe that God does not exist, or maybe they believe in teachings of Buddha, it is all the same to the world. What is important in life is not do you believe in good or now, it is important not to cause suffering to other people and even more important that this one before is that you are happy with you life. There is nothing more to this mortal life than that...
Right. You can believe in anything only so that it does not harm others and not impose your own way of life on someone.
What do you ever seen believers who do not impose their faith to others? Every religion encourages its parishioners for what they bring to them new people. So they always try to impose the religion of others and to appease this God of his.
