Please present positive arguments why you think atheism is true

[Darwinian]

So any credible evidence on hand for naturalism ?

Yes, the fact that the Universe looks and behaves in exactly the way it would if there were no god...

If the Universe did not operate on naturalistic principles but instead was guided by the whims of a divine creator then we could never make any accurate predictions and science itself would make no sense. The fact that we can formulate laws and theories and use them to accurately predict and understand such things as orbits, eclipses, weather patterns, animal behaviour, social dynamics, financial trends, plate tectonics, time dilation (re: Satnavs), tides (O'Reilly take note), animal migrations, the outcome of mathematical equations, atomic decay, biology, natural history, physics etc. etc. points to the inevitable conclusion that either there is no guiding hand of the divine or that hand stopped guiding at the point of the big bang!
