Who told you that the flagellum was in the first cell? They lied to you. I checked out your article and it is sadly full of lies. They started by lying about the purposed of the Miller-Urey experiment. It was an astoundingly successful experiment since they proved what they set out to prove.
I gave you links to real science based articles that explain how the rotator flagellum evolved.
Why on Earth do you believe the nonsense from those lying sites? Don't you know there is even a law against it in your big book of myths?
I was going to recopy the yuotube site + 200 peerreviewed scientific papers you gave about 600 posts back, but my computer does not coöporate and decided that the definition of theopneustos was more relevant. l.o.l.
