The Fine-Tuning Argument

[Kim]

I think the gist of the fine-tuning claim is that the universe would be a very boring place, devoid of any sort of complexity, if any of the many fundamental constants are only slightly changed. I have to see yet a clear and straight-forward rebuttal to this claim. Most of the responses thus far in the line of:

1. This is how the universe is.
2. There could be multiverse, each with different constants, and we happen to live in one that supports complexity.
