After having a look at the website about UFOs
In this site(http://aliens.monstrous.com/roswell_gallery.htm), there were some pictures of aliens lying on the operation tables. Some aliens were in the process of being anatomized. Most of them were pale, thin, and they had big eyes and heads. And they were as big as 10 year old boys. There also were pictures of UFOs. Most of them just looked dish-shaped. Mostly there were one or two UFOs in the pictures. Strangely, there were many UFOs in the picture of the White House.I believe that there exist aliens and UFOs. But I don’t believe that all pictures are true because some of the pictures turned out to be untrue. And also I don’t think that aliens look like the appearances in the pictures. Aliens in the pictures are similar to aliens in some science fiction or cartoons. The pictures in the website is not believable. But I still believe that there are aliens and UFOs because there is no evidence of not existing of aliens and UFOs.
