We have lab environments that can reproduce any of the physical conditions required which might be required to create a simple life form, from inorganic matter. To say that this was a one time event, which can't be reproduced in a lab, is preposterous. The fact that scientists have not reproduced life through heat, electricity, and just the right combination of elements, implies that maybe there is a factor that they have overlooked. To simply state that life popped out of a stew, with absolutely nothing to back up that assertion, isn't testable, nor reproducible.
