Has Science done away with a need for God?

[Esquilax]

I'd also like to add that this "complexity equals design!" argument fails to take into account emergent complexity; that is, complexity that results over time due to an expansion or collection of simple things. It assumes that the universe was always complex, which we know was not the case, given that prior to the big bang all we had was a dense point of spacetime. The universe gained its complexity over an extremely large span of time via the interactions of very simple things. All that we see now simply was not present at the beginning of the expansionary universe, it formed over time; we didn't even have heavy elements in the early universe.

So even if your argument is that complexity is an indicator of design, I simply have to point out that this complexity is demonstrably an emergent property that was not present at the time that our current universal state came into being. Even if the argument stands, which it doesn't, it's still wrong. There is literally no sense in which the OP's position is even a little bit correct.
