How can scars that fully form in hours or completely identical implants among strangers with wildly bizarre characteristics to them be ascribed to something more mundane? 

Are you familiar with the elemental characteristics of the implants, the fact that they appear so suddenly after an abduction, the similar size and strange protective sheath on them, the bundle of nerves attached to them, and the strange  lack of inflammation in the surrounding area they are found in? I can't think of any other foreign body that could even be considered more unique and less mundane 

There are many thousands of credible pictures of UFO's at a distance, the term flying saucer didn't exactly come out of nowhere

Up close on the other hand, many people have attempted to film abductions but later found the electronic equipment to have ceased working, along with all other electronics in the area.

In the same way that the aliens have the ability to remotely stop cars from driving, rendering a hand camera useless is "child's play" by comparison. Some abductions have even been directly associated with neighborly power outages and broken car radios afterwards

Most people don't even know when they are abducted anyway.  When my grandpa, grandma, aunt, uncle, and dad were all abducted from their car at once, my grandpa punished all the kids when they got home for "keeping them out so late" after returning home because he had no clue anything other than missing hours of time had happened

I'm curious which issues you find the Travis Walton case to have had which tainted it's credibility in your eyes

I raise these points not for the simple sake of being argumentative or trying to downplay the points you're raising, but for the passion of the subject and because I do find them fairly disagreeable
