5Many scientists believe that, due to the sheer [blank_start]size[blank_end] of the universe and the fact that there are so many [blank_start]galaxies[blank_end], it is highly probable that there will be [blank_start]life[blank_end] on another planet somewhere. Even if a small [blank_start]proportion[blank_end] of stars have extrasolar planets orbiting them, many scientists believe that it is likely that life already [blank_start]exists[blank_end] elsewhere in the universe. However, as yet [blank_start]no[blank_end] evidence for [blank_start]extraterrestrial[blank_end] life - either at present or in the past - has been detected.
