“Why would that be any different than our experience here on Earth? At what point did we progress from non-life to what we see around us today?”
If you could scientifically establish the answer to that question, you’d probably win a Nobel prize. As of yet no scientist has been able to do that though.
“So we must have made the progression...”
See, this is what is known as a non sequitur, because the conclusion does not follow from the preceding data. Just because there was a point where there was no life on Earth and now there is life doesn’t automatically lead to the conclusion that life sprang spontaneously from non-living material. Science cannot establish that it is even possible that such a thing could happen, and they also cannot rule out the other possibilities that might account for the origin of life. So as soon as you make this assumption, you have ceased to make a scientific, or even a logical argument.
