As a chemist and then chemical engineer - It's easier for me to believe that a freak incident that cause all the stars and matters to line up in just the right way than for this fantasy -
life was brewed in a torrid mix of chemicals and lightning in the mud and oceans of
and to create even just one DNA molecule.
And, remember -
"what came first? The chicken or the egg?"
Now extend that a million times❗
The next question -
What came first? The life-form or the DNA that makes it?
And, I'll need the process and the numbers - time, materials, energy, the steps and the numbers of steps and their sequence❗
This is much harder to have a randomly chosen group of people to perform a play without a plan or script and expect a perfect performance out of it.
I'll even back off from the main issue -
Life can only come from life❗
As I said, if God created life on earth, why would he stop at just one planet. If you were growing flowers in your garden, you would not stop at just one seed.
I will therefore argue that if God created life, he created it everywhere. He created it on all the habitable planets in the universe. Therefore, my argument that we are not alone stands, even in a biblical sense.
There is no if in this - our eternal life, life after death on earth, depends on this belief.
