Atheists are very intelligent people and always have a scientist nature. They don't accept any thing blind unless it is proven.
Religion is a different business, its all blind , only past and future. past stories and future next world scares. There is no present in any religion about businesses, education, democracy, banking, currency or property management, because its all too complex for religion to handle it. There fore atheists are not convinced they just go quiet.
Indian Bollywood made a good movie titled "' OMG". ( Oh My God ), when a businessman suffers a loss due natural calamity, he demanded God to payback but couldn't. he filed a legal claim in court and all so called agents of religions were called to pay as agents since they always collect donations and zakat etc. An interesting movie.
Btw, most young generation of today and future is atheist in the literal sense. Mostly because agents of God can only talk about thousands years past saints and million years ahead future of hell or heaven.
