Okay, I'll grant you that if someone only believes in a God creating conditions for life then the Anthropic principle sort of suggests a non-God possibility, along the lines that Evolution with natural selection presented a way for increasing complexity and intelligence to arise from random mutations without an intelligent designer.

Still, we humans exist in a visibly large and competitive 'dog eat dog' ecosystem, so observing that the ecosystem affects the life within it is a certain kind of idea which fits in with a lot of other observations. Your comment line which I quoted above assumes a low-probability event based on no other observations, when there's no reason to assume that, no sign of an 'evolution of Universes competing in a wider ecosystem of Universes'; you've declared this universe to be 'low probability' based on nothing and then seek to explain something about how we find ourselves in a low-probability universe. For all we know, this could be the only possible Universe configuration, the only solution to some Universe-equation, or an overwhelmingly likely one if all possible Universes are capable of supporting life [and the ideas of Universes which couldn't support life are, in some way, not possible].
