If you wish to remain atheists don't read this.
For those who don't mind Science and Creator. I am in the middle of this article and its is the best I have ever read on explaining the science.

here is a an excerpt...
"Mass of the Universe
Astronomers have discovered that the total mass of the universe acts as a catalyst for nuclear fusion and the more massive the universe is, the more efficiently nuclear fusion operates in the cosmos. If the universe is too massive, the mass density too great, then very quickly all the matter in the universe is converted from Hydrogen into elements heavier than iron, which would render life impossible because the universe would be devoid of Carbon, Oxygen, Nitrogen, etc.
If the universe has too little mass, then fusion would work so inefficiently that all that the universe would ever produce would be Hydrogen, or Hydrogen plus a small amount of Helium. But there again, the Carbon and Oxygen we need for life would be missing.
What does this tell me about the Creator? That God so loved the human race that he went to the expense of building one hundred billion stars and carefully shaped and crafted those hundred billion trillion stars for the entire age of the universe, so that for this brief moment in time, we could have a nice place to live.

We live in a Special Solar System, Too
We can extend this argument of design from the universe to the solar system itself. When we look at the solar system, we discover that we have a heavenly body problem. Itâs not that easy to get the right galaxy.
Life can only happen on late born stars. If itâs a first or second-generation star, then life is impossible because you donât yet have the heavy elements necessary for life chemistry. Thereâs a narrow window of time in the history of the universe when life can happen.
If the universe is too old or too young, life is impossible. Only spiral galaxies produce stars late enough in their history that they can take advantage of the elements that are essential for life history, and only 6% of the galaxies in our universe are spiral galaxies. Of those 6%, you must go with galaxies that produce all of the elements that are essential for life. Itâs not that easy.
Besides Hydrogen and Helium, the other elements are made in the cores of super giant stars. Super giant stars burn up quickly; theyâre gone in a just a few million years. When they go through the final stages of burning up their fuel, they explode ashes into outer space, and future generations of stars will absorb those ashes."
