If the universe wasn't in a position to support life, this argument wouldn't exist, because life wouldn't exist.
Douglas Adams parodied this argument:
Put simply, the only reason we consider this to be an argument is because we are here, and we can't exist if the universe were somehow tuned some other way. It doesn't mean the universe was tuned *for us*; it just means that we are possible because the universe is like this.
Douglas Adams parodied this argument:
Quote:Imagine a puddle waking up one morning and thinking, 'This is an interesting world I find myself in, an interesting hole I find myself in, fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!' This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, it's still frantically hanging on to the notion that everything's going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for.
