With respect to you, you're putting the cart before the horse. This is the correct way around:
1. Our sun is very stable (out of the trillions of suns in the universe).
2. Therefore life can exist on Earth.
But in this article, you've got it the wrong way around:
1. Life exists on Earth.
2. Therefore the sun must have been designed specifically for life to exist.
Do you see the error in your thinking? The stable sun came first, which led to life existing. It's a very straightforward idea. Your idea of a creator making a stable sun just for us on Earth is a much more complicated and messy way of thinking.
I believe in Gods, monsters and the rootless root, so I am not secular, but you must hone your critical thinking skills whether you believe in the gods or not.
