According to this article 'Alien spies live among us' says Bulgarian gov space boffin:
"The star-travelling aliens have long ago graduated to advanced energy sources such as nuclear fusion or antimatter, and sneer at our pathetic fossil-fuelled civilisation.
Filipov stated that the alien spies in our midst have other objections to our lifestyle, too.
"They are very skeptical of our use of cosmetics, and artificial insemination because this is unnatural," he reportedly said."
