The EBEs interest is on "Soft" or Bio-Technology
|The EBEs interest is in "Soft" technology while Human interest has been primarily directed at acquiring "Hard" Technology.
Human abductions, cattle mutilations and organ harvesting show that the EBEs are focused on improving or surviving their species. Humans tend to take their life form more for granted and show greater interested in the hard technologies of space travel.
It would appear that the two races have been introduced with opposing values regarding their vital interests. This is not to say that Humans are uninterested in the soft technologies. Clearly mankind stands to gain from a better understanding of what the EBEs are up to. Medical science is a booming business and independent of any alien interest, mankind has long strived to better understand how life works, specifically in regard to the human genome.
