you are in trouble, but please don't say you are 100% non believer of god,
i'll say there are two different ways, 1. believing god is exist who created all life , animals, nature, humans, universe like anything
2. man made gods like jesus, Allah, buddha, zeus, shiva, etc...
you no need to follow mad made gods and religions,rules because they can't prove those god is exist, i 'll ask one question Jesus can't even save him from Jews then how he going to save all Christians and he is just a man who do social service and help others and stand against Jews so followers created one story and later he become a god.
we can think some power is apart from us which given gift planet like earth to humans.. no need to worship and follow,nothing is use.. better for that we can help poor, plant more trees, helping for orphans educations but these things will make us happy and they will smile because of you.
helping others will make real happy . god is love and love is god. god is nothing for us. if we live good in this earth is enough. if you pray or sacrificing anything will god give you power to kill titans,devils..
following religion is waste of our life period. nothing is use..
there is no heaven or hell. we are already in heaven earth . our life is only for few years why should we waste time just have a beautiful life and enjoy.
Adam and eve -moses - Jesus - Mohammad- all are good mans want to make a new way for mans,so our mad humans created them as god. if mother Theresa born before some 1000 years back she will be also one of gods. gods and religions is only for money.
