As an amateur anthropologist I see evolution at work here. The girls all go for his boyish looks and obvious intelligence and the boys who are in direct competition with him will put him down to elevate their chances at procreation. We humans do this unconsciously! I am not jealous of him at all!

I have to think about the existence of the meteorite and an early thick atmosphere. I am sure it is more complex than what we think. With such a thin atmosphere and a shallow angle could lead to the asteroid having enough velocity for gravitational escape.
