Question

review the fourth paragraph. there is actually long - standing evidence that alien life has already made its way to earth. for example, many have long asserted that area 51, the highly classified u.s. air force base outside las vegas, nevada, houses such evidence. while numerous ufo (unidentified flying object) sightings have been reported in the area in recent decades, the u.s. government maintains that the details of area 51 are classified in order to protect national security. this response, along with numerous claims of alien sightings across the country, has fueled speculation that officials have already uncovered evidence of alien life. for nasa, however, the focus remains on finding alien life elsewhere in the galaxy. nasa has continued to roll out plans to search for signs of life on both mars. the fourth paragraph is meant to support the authors main claim that it is likely that alien life exists beyond earth. whats wrong with the authors argument in the fourth paragraph? the author fails to offer a reason why aliens who reached earth would choose to visit area 51. the fact that many people have claimed aliens have reached earth is not evidence that its true. the idea that area 51 might hold evidence of alien life is not relevant to the main claim.

Explanation:

The author uses claims of alien sightings and speculation about Area 51 as evidence. But just because many claim aliens have reached Earth doesn't prove it. It's anecdotal and not conclusive scientific evidence.

Answer:

The fact that many people have claimed aliens have reached Earth is not evidence that it's true.
