I know that there are already 'evidence of ETI' threads, but I thought I'd try and begin this opposite thread, outlining why I find the widely-reported ETI visitations difficult to accept. So here goes...
Interstellar travel: I know this is being argued round and round even now, but I shall say it here anyway: I do not believe that the vacuum energy will ever be exploited as a power source, and I am very skeptical of the belief that gravity and inertia will one day be manipulated. However, I don't deny that interstellar is possible.
Anthropomorphic aliens: The image of the classic, X-Files style 'Grey' alien makes me laugh. There are even meant to be aliens indistinguishable from humans! Look at the huge diversity of body shapes that nature has created on Earth. Now imagine a creature which evolved around a different star, and with which we share no common ancestor. Is the result a 'Grey', or another person? I understand the concept of convergent evolution, but these things even have eyes, noses and mouths in exactly the same configuration as us. This takes me onto my next point...
Alien motives: I'm aware that there's already a thread specifically on this subject, but I thought I'd include it here anyway. It seems that the explanation given for many abductions is one of genetic research and hybridisation. We are led to believe that of the myriad amino acids available, the hereditary material of these aliens is based on the exact same four as our own, and that we are somehow compatible for cross breeding experiments.
The purported aliens travel God-knows-how-many lightyears to perform aerobatics in our skies.
To preserve their secrecy, when they abduct people they wipe their memories but leave scars and burns. These memories arise later during hypnosis and the world learns the truth. Haven't they heard of general anaesthetic?
I am interested to hear your views on these points (although I think people may have to just agree to differ on the likelihood of harnessing gravity and the vacuum energy).
