However, speeding up atoms corresponds to a temperature increase. One of the conditions that must be correct for life to form is the environment must have the correct temperature. If you speed up your atoms too much, life will not form because the temperature will be too high. Therefore, your idea of speeding up the process of life formation will not work.
So if doing something faster won't work. And doing it the slow way is yet to yield result that we've observed... why would thinking Life came about in and of non-life be scientific?
Also, wouldn't the idea of radiation and lightning causing life in "soup" mean that heat incourages life? Can't things live in several hundred degress Celcius?
There was an article posted last week saying bacteria had been found living in ocean trenches at 750 degrees. Bacteria at Yellowstone can live at 30 degrees above boiling.
