I also failed to catch the "proof" that was supposed to be in that article unless it was the assumption that ALL evolution, change, adjustment, or engineering change in "life" had to have taken place on Earth!

It's a real leap of faith to believe that in such a large universe (of which only 2.5% is ever going to be accessible, sensible or visible to us) that life wasn't developed/designed elsewhere, probably several times. No doubt it will even outlast the heat-death of the present physical universe in which we find ourselves ~ it's that well designed!

The proof of what? I'm rather confident that this relatively modest research study does not aspire to proove that ALL evolution, change, adjustment, and engineering change in "life" had to have taken place on Earth. I would hope not, at least, because that is almost certainly not true and impossible to prove even if it were..
