As an atheist I have to accept that the 'Big Bang' (or whatever other start to the Universe, and to life, you happen to believe in) MIGHT have come about through the actions of some supernatural being (who, if you like, I'll call 'God').
However there is no scientific logic to assuming that a 'Creator' would have any further interest in his (or should that be 'its'?) creation. A scientist might create life in a test tube but then walk away from it and take no further interest in its development. There is certainly no reason to assume that the scientist should seek to become a 'moral arbiter' of what happens within that test tube.
Further, your question makes assumptions by the use of the phrase 'adjust accordingly'. If there really is a 'God' who wants us to conform to his requirements, why should I assume that those requirements are the ones specified by Christianity, Islam or any other religion? Perhaps (as nature and evolution seem to indicate) God simply believes in the survival of the fittest? If that's true I should 'adjust accordingly' and arm myself with the most powerful weapons available and destroy everyone who gets in my way.
