Does believing in God require blind faith? Do we have to choose between science and faith? Is God real? It’s the most important question to answer in life. If He doesn’t exist, we can carry on the way we are. If He does exist, our eternal home hangs in the balance. One thing is clear though, burying our heads in the sand doesn’t make it true or untrue — it just makes us uninformed.

Come on, let’s explore the evidence. Stick with me, this is going to blow your mind!

Is there proof God exists?

We’ll start by looking at the big picture and then narrow the focus each step of the way. First, we’re going to get our science on and then talk about the accuracy of the Bible. In order to contain these topics to one blog post I have to be ridiculously brief, but I’ve tried to offer extra resources if you’d like to dig deeper.

This is not over your head, try to soak it all in with a clear mind. I promise this will get you thinking in a fresh way. I’m so excited, let’s go!

This is a four-part series:

There are at least 30 parameters for a life-sustaining universe


Is our home planet the result of cosmic happenstance? One thing everyone can agree on is that the planet Earth is not ordinary. It is the only known planet able to sustain life. Let’s see what makes our home so special.

There are at least 30 parameters for a life-sustaining universe. If you wipe out one, there can be no life. The laws of physics are balanced on a razor’s edge for life. Here are a just a few powerful examples:


Gravity, as we know, is what pulls matter together. Without it, there cannot be planets, stars or complex organisms. If you change the force of gravity within one inch, anything larger than the size of a pea would be crushed.¹

“Imagine a ruler divided into one-inch increments and then stretched across the entire universe a distance of some 14 billion light years. … The setting for the strength of gravity could have been anywhere on the ruler, but it just happens to be situated the right place so that life is possible.” — “A Case of A Creator,” film by Lee Strobel

Expanding speed of space - Cosmological constant

Expanding universe

The cosmological constant is the expansion speed of space. Space was once thought to be static, but now (thanks to Hubble and Einstein) most scientists agree that it is ever-expanding. If space expands too quickly, the universe (galaxies, stars, planets) can’t form. The cosmological constant is fine tuned to 1 part in 100 million billion billion billion billion billion. Did you take that in? ¹


“The precision is as if one could throw a dart across the entire universe and hit a bulls eye one millimeter in diameter on the other side.” — Michael Turner, astrophysicist

An inhabitable planet

There are about 20 characteristics of a planet that can sustain life, such as these:

  • an oxygen-rich atmosphere
  • liquid water
  • large continental land masses
  • a home star of the right temperature and mass
  • an orbital path that is neither too far nor too close to the home star
  • a moon large enough to stabilize the tilt of planet’s axis and its tides
  • a magnetic field strong enough to deflect the sun’s radiation

The chances of all the necessary factors to sustain life appearing at the same time on the same planet are ¹

Next: Is life an accident? >>

That’s just a tiny sample of our environment’s fine tuning. Next week let’s look at life itself.

Could we have come from a fish? Apes? How did we get a conscience? What defines right and wrong for us?

We’re even going to talk about the golden ratio that is found in the shells, sunflower, pinecones, the galaxy, a hurricane, an unfurling leaf, petals, even the ocean waves!
