Although a majority of those surveyed, 53 percent, said they do not believe in aliens, 23 percent expect an alien civilization to contact humans, the Russian news agency RIA-Novosti reported.

Its findings were reported shortly after an influential Russian Orthodox Church official commented that people often mistook angels and demons for aliens, RIA-Novosti said. The poll of 1,500 respondents has a margin of error of less than 5 percentage points.
