Why not? Also you are missing something my friend. Namely the fine tuning of the very constants of the universe itself - not just the planet.you can't talk about evolution anymore.
second, just because this planet is suited for life, doesn't mean there's a god. there's an infinite number of other explanations, all of which have just as much credibility as the existence of a god. so why pick that one? cause you were brainwashed to believe it.
The problem here is that you are just saying **** and talking out your ***. You assume I was somehow brainwashed, were you not? I study cosmology and see that despite many attempts no one was ever able to get around the initial singularity in the Big Bang model. The problem here is that the universe began to exist, the constants are all perfectly in place without any reason to be caught in this place. Even stranger is the fact that minute changes make life impossible. So how do you explain this?
You can't explain in naturally. You can't. What is natural started at the Big Bang. Why don't things pop up into existence all of the time? What begins to exist has a cause. The universe began to exist. You cannot explain why the Big Bang happen, in fact what you believe is worse than magic, honestly. Theism is not always as stupid as you want to think.
