Here is a video that was posted by the YouTube channel called Top3s. It shows 3 times in which supposed real life aliens have been caught on tape. Whether or not these clips show real aliens is totally up for you to decide, however there is no denying the scare factor in some of this footage. Do you believe that aliens are visiting Earth? This video attempts to make the case that they not only have visited Earth, but they have also been documented on video.
