Has Science done away with a need for God?

[Kingpin]

Apart from splitting hairs about the definition of God etc., though, I think we can safely say that there are several important thinkers in history who would have been full blown atheists if the had known what we know today about evolution by natural selection. For example, I recall Voltaire saying in his philosophical dictionary that he cannot reject God because of the apparent design in nature. I take this as an admission that he would favour being an atheist if that issue had been taken care of. I guess the same would have pushed more than one Deist among the US' founding fathers.


edit:

Voltaire repeatedly talks about the moral dangers of atheism - however, I cannot believe that he was so shallow a thinker that he would seriously argue that atheism must be false because he dislikes the (imagined) consequences.

"The atheists are for the most part impudent and misguided scholars who reason badly, and who not being able to understand the creation, the origin of evil, and other difficulties, have recourse to the hypothesis of the eternity of things and of inevitability. "

"Let us add especially that there are less atheists to-day than ever, since philosophers have recognized that there is no being vegetating without germ, no germ without a plan, etc. and that wheat comes in no wise from putrefaction."

The only real argument against atheism I recall him making was the one from design.

I always found it fascinating when people bring up Voltaire and how his argument from design would not stand against today's modern scientific achievements but quite often people either forget and completely ignore modern atheists arguing and admitting the argument from design still stands.  Do we forget the most notorious atheist of the 20th century conversion to Deism, Antony Flew when he said:

‘almost entirely because of the DNA investigations. What I think the DNA material has done is that it has shown, by the almost unbelievable complexity of the arrangements which are needed to produce (life), that intelligence must have been involved in getting these extraordinarily diverse elements to work together. It’s the enormous complexity of the number of elements and the enormous subtlety of the ways they work together. The meeting of these two parts at the right time by chance is simply minute. It is all a matter of the enormous complexity by which the results were achieved, which looked to me like the work of intelligence’ (p. 75)

Richard Dawkins has also stated that one could make the argument that there appears to be design in the universe.  Stephen Hawking also stated that the universe appears designed, but again both argue that this is not evidence for God.  I am not espousing that either, just pointing out that the "design" argument even today still holds weight.
