Strong anthropic principle is really good argument for creation

Strong anthropic principle is really good argument for creation, moreover its refuting trials are not that good.

According to Sir: Martin Rees, there are 6 quantities that are tuned in our universe to adapt life. Epsilon, N, Omega, Lambda, Q and D.
He invented a smart idea to refute creation though these six parameters are tuned for life. He suggested that there are infinite universes that have different combination of these parameters, but it is natural that the only detectable universe is ours because the rest has no life to detect!!
The problem here is that atheists see that detectability and falsifiability is the basis of existence evidence, and they omitted God existence based on them. So what about Sir.Rees? Why does not he apply the two principle on his infinite universes, so he is in contradiction, to avoid God existence he had to assume existence of infinite non detectable unfalsifiable entities!!
