Theists, when you make this argument, do you not realize that you're trampling all over your god's omnipotence? If the universe was made for life, with all the universe's dangers and inefficiencies, then to say that it could be no other way is to say your god couldn't do it any other way - and obviously, a way less hostile and more conducive to life would have been a better way.
I'm shocked people still use the fine-tuned universe argument. Though this counterargument is hardly new, I thought it would be fun to give it the DarkMatter treatment.
Here's two other videos I've made which address the fine-tuning argument more thoroughly (as some theists believe this video is a bit of a strawman):
A couple questions for creationists: Was Adam flesh and bone? If you dropped him off a 100 foot cliff before he ate the fruit, would he have died? If lions weren't carnivorous before the fall of man, then please explain how a man eating a piece of fruit would cause the digestive systems of large cats to be permanently altered, and why we've never found the fossils of such cats. What is the purpose of an extinct species? Why did God condemn 99% of all species that have existed thus far to extinction? Why did he design them in the first place if He knew that they were going to be unsuccessful (though, humans aren't yet nearly as successful as some species that have survived for many millions of years before their extinction)?
