Personally don't know much about start of life on Earth, but I'm intimately familiar with the end of life in my homeland of Iran, for the past 38 years.
Historically speaking mullahs have always had aspects of pests and estranged elements. But in the past 38 years with the extent of thieving, sleaziness and sheer scum they've committed they definitely qualify as bugs, big bad bugs. And by now they've also thoroughly alienated themselves from the people.
In conclusion: we have had alien bugs ruling us, almost four decades now!
