50% of the scientists believe that  these objects have been around for years. i actually think they r real too. there have  been many cases where people said that they have see UFOs. But no one has actually found a solid proof to prove they r real. late in the 80’s a UFO was seen in California and a proof was found for it and some of the scientists researched it and some of them were saying it was actually true. this was also posted in the news papers and people started to get scared. this caused the research to get shut down and has been requested by many scientists to reopen it but the us government is not allowing permission. this means that there could actually be UFOs. now another question, if there are UFOs and there r another kind of humans, are they the same like us. Will they try to attack us? there will always on danger, maybe they know about us and are planning to attack the earth. this could cause a huge destructions because if they have the technology to come to earth from a far distance the can mostly do anything. so its either a bad thing or a good thing for us to come in contact with them. post comments.
