In general people lack proper arguments for what they believe. most people either point to their church leader and say they are right or scienceguy and say they are right because they dont want to go out on their own and make a choice of their own. A lot of people wear religion like a costume and wear 'spirituality' as a fashion accessory, i find this a lot with 'pagans' or 'wiccans' who lack any genuine spirituality but cover themselves with tattoos and bullshit symbols they dont understand just like faggots with chinese symbols. Same goes for christians for that matter who take the lords name for nothing more than vanity. I think a reductionist version of the argument is: Do you believe in 'a creator that created reality on purpose from something' OR that 'there is no creator and we happened on accident from nothing?' One sounds reasonable, the other completely absurd. Theists attempt to understand the creator, why we were created and what purpose we have, atheists have nothing to contemplate. At the end of the day there is no creator revealing himself to us and answering these questions, so we are left putting the pieces together ourselves, often relying on the testimonies of people who say that they were spoken to and had the questions answered. Frankly though i think anything is better than atheism, atheism is brain death.
