In total, 521 astrobiologists responded, and we received 534 non-astrobiologist responses. The results reveal that 86.6 percent of the surveyed astrobiologists responded either "agree" or "strongly agree" that it's likely that extraterrestrial life (of at least a basic kind) exists somewhere in the universe.
When we turn to "complex" extraterrestrial life or "intelligent" aliens, our results were 67.4 percent agreement, and 58.2 percent agreement, respectively for astrobiologists and other scientists. So, scientists showed notable agreement regarding the potential existence of more advanced forms of alien life.
