I remain a skeptic regarding the "alien photos" that i have seen because there is a certain ... I don't know, maybe fake look about them. Older pictures are so grainy and only show bodies that could have been molded as a prank gone out of hand. As to more modern pictures, I remind you of the G.E. commercial with the elephant dancing in the rain forest to "Singin' in the Rain." That is a high-res, incredibly life-like CGI demonstration that blew me away the first time I saw it. I had an uncle (now deceased) who, if he had lived to see that, would have cried at the cleverness and beauty of the work.
I am not saying that aliens don't exist. I think that there is no particular reason (perhaps other than morbid fascination, which is a grim thought unto itself) for them to come down for a visit. We shouldn't have bodies. And if they are clumsy enough for US to catch them, then how precarious are their ships? It makes no sense. Look back at the work we did for ten years just to get a moon landing! Look at the work we have done for decades to have a few Mars landings. An interstellar voyage would be a phenomenal effort by our standards. I simply remain skeptical over the evidence.
