I make the case here and here.

Hmm. I see references to the oft misunderstood (by creationists) Cambrian Explosions, and several appeals to argument from incredulity, but I don't see anything in there that specifically shows how common descent requires that life originally come to exist through a specific method.

Why not just tell me straight up. Let's say that one day we discover that life came about through some other method than the one you think common descent requires. Maybe a divine agent zap-poofed the first life forms into existence. How would this falsify common descent? Maybe in the future humans travel back in time and planted the first life forms. How would this falsify common descent?
