The Town of Roswell, New Mexico is planning for its yearly Alien Festival. If more than 40% of adults believe that UFOs are related to aliens from other planets, it plans to give vendors at the festival a greater tax incentive than last year to bring in more vendors. The town will utilize a Gallup Poll to decide which says the following. "More Americans are taking UFOs seriously than just two years ago. When asked which of two theories better explains UFO sightings, 41% of adults now believe some UFOs involve alien spacecraft from other planets, up eight points from 33% in 2019 . Half of Americans, down from 60% in 2019 , remain skeptical, saying all UFO sightings can be explained by human activity or natural phenomena. Another 9% are unwilling to venture a guess. Results for this Gallup poll are based on telephone interviews conducted July 6-21, 2021, with a random sample of 1,007 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia."
