Way back, I wrote about how Evolutionists still believe in spontaneous generation, just giving it a new name: Abiogenesis. That post mentioned Pasteur a bit and included a picture of one of his experiments using “swan flasks”. Ever since then, I’ve had a trickle of people searching for info about Pasteur’s flasks.

Eventually, I got so curious I did some searching of my own. Here’s what I found:

Louis Pasteur

Darwin’s Origin of Species book retelling the ancient idea of biological evolution was first printed in 1859. From the beginning, many people recognized what believing in life creating itself would do to Christianity and human equality, including Louis Pasteur.

Just a few years before, Pasteur had begun studying how microbes (tiny living creatures like bacteria and yeast) were the cause of food spoilage. He was in a perfect place to understand what Darwin was claiming and the scientific truth about life. He was soon busy showing how impossible the #1 necessary step of Evolution was: getting life to start in the first place.

Others had tried to show whether microbes just popped into being whenever things were right or not. But no one really knew how these invisible things worked and they made mistakes like letting air in or not heating things enough to kill everything.

We all understand what Pasteur was the first to figure out: you don’t have to touch something dirty to get germs on you. Bacteria and viruses float around in the air ready to settle into a pleasant environment like your lungs and nose.

Pasteur proved this when he managed to catch some microbes from the air in cotton. He cultured the cotton and it grew the same kinds of microbes as usual. Now it was time to see if stopping those airborne germs stopped life from starting in a flask.

Here’s how Pasteur did it:

Français : Le célèbre

  • First he made flasks with bent, “swan”, necks. This was to trap all the organisms in the air before they could get through
  • He filled the bottom of the flask with some broth microbes liked to grow in
  • Then he boiled it to kill anything already there
  • While it was still hot, he melted the glass at the tip of the neck to keep microbes from getting in

nothing grew in the broth

  • Even when the sealed end was broken off, the swan neck did its job

still nothing grew in the broth

  • Finally, Pasteur tipped the flask to expose the broth to the trapped microbes

sure enough, it started to culture just like usual

To this day, evolutionists don’t like to talk about spontaneous generation; most books skip right over it to the “first cells”. The most recent experiment “proving” you could get life to start from non-life is over 60 years old. Scientists have even turned to asteroids to give them enough time for the impossible to happen.

But, nature serves its Master whether people are willing to worship Him or not.

Let God be true, but every man a liar; as it is written, That you might be justified in your sayings, and might overcome when you are judged. Romans 3:4

You can do Louis Pasteur’s experiment for yourself with the right supplies. This article on how to do it at Biology Junction is worth the read even if you don’t have a lab.

There’s also an interesting 7 minute video about the Swan Flask Experiment at the Education Portal.

Did you notice how much these pages sound like creationists? The people who believed in spontaneous generation are rightly seen as ignorant of reality.

I found a lot of information for this post in the Answers Research Journal article by Alan L. Gillen and Frank J. Sherwin III: Louis Pasteur’s Views on Creation, Evolution, and the Genesis of Germs

    Great stuff! I am excited about using this information with my church adults. People need to know that there is scientific evidence that points to Creation. Love this. Thank you!
