Trouble with all of those arguments is that they're based on the science that we know, and based on the laws of physics which we're subjected to on Earth. But the whole point of aliens is that, well, they're alien. We don't know about them, they're different. UFOs are UFOs because they're unidentified. This particularly pisses me off when scientists write off whole planets or star-systems as incapable of supporting life because there's no oxygen or water. Bollocks! How self-centred is that, to rule out so much just because WE need water and oxygen and whatnot to survive. Doesn't mean other beings elsewhere need them, and likewise on the physical experimentation argument, maybe there's a reason 'they' would use anal probing or whatnot as opposed to scans. It seems to me that we rule out a lot of possibilities through our own self-centred egotistical nature and refusal to even entertain other possibilities which are beyond the knowledge we have.
