|[qs]You have to face up to the facts if there is no known or at least plausible mechanism that could account for a spontaneous generation, we are left to conclude that a higher-intellegence is responsible for life.[/qs]|
A thousand years ago there was no known or at least plausible mechanism that count account for lightning so our Viking friends concluded it was Thor throwing hammers at the giants. They were wrong.
In fact, the history of science is littered with such examples, once upon a time people in their ignorance concluded that some supernatural entity or doodad was responsible for the things they couldn't explain. Time and time again they've been proven wrong by scientists working away at a problem until they find the answer.
What reason can you give to believe that in this case not knowing how it happened should lead to the repeatedly discredited conclusion that goddidit?
