Take it easy he is still alive. The Carbon based life form you thought was 4E never existed. In actuality he is an ancient member of an intergalactic consortium charged with determining the viability of burgeoning civilizations.
He arrived on our planet after an earlier exploration claimed that our species should be destroyed. Well, being the scientist that he is he decided to see for himself. He landed on out planet some 300,000 years or so and immediately took a liking to our female species–little did he know that there was some incomparability between his people and the hairy earth hominids he liked so much. Many perished because his love force was too strong but this forced our species to evolved. Currently the only side effect is that our women develop KNEE issues if they mate with him
Sadly, 4E study of humanity led to the conclusion that Humanity is too dangerous to be allowed to spread to other planets. So 2 days ago he left the planet and took 2 humans, Kanye West and MRS 4E, precisely in that order.
The reason he recommended, as stated in his report, the earth be destroyed was simply:
Hillary Clinton and Donald Trump.
