“外星人”其实是为了躲避地球物种大灭绝,才从地球上逃走的。但不久之前(大约恐龙时代时)他们的科学家在地球上搞了一次全球性的进化实验。他们在不同地区,为不同物种都注射了某种药物,这可以使与他们有近亲关系的物种快速进化,从低级到高级只需几百年甚至只有几十年。成功后,他们会为自己注射,这样他们的智商会越来越高。当然,他们还会定期派UFO来抓几个试验品后代来研究实验效果。 “Alien ” is actually in order to avoid the extinction of Earth Species, only to escape from the earth. But not too long ago (about the time of the dinosaurs) their scientists engaged in a global evolutionary experiment on Earth. They inject different medicines for different species in different areas, which can make the species with their close relatives rapidly evolve, ranging from low to high only a few hundred years or even decades. After they succeed, they inject themselves so that their IQ will be higher and higher. Of course, they also regularly send UFO to test the descendants of several experimental products to study the experimental results.
