  Oumuamua, the first known object of extrasolar origin seen to enter our Solar
System, has multiple unusual characteristics that, taken together, are very
difficult to explain with conventional astronomical entities like asteroids and
comets. Consequently, it has been hypothesized that Oumuamua is an interstellar
probe that was constructed by an alien civilization. We demonstrate that the
accomplishments that can be achieved with large space telescopes and
interferometers in the alien's planetary system will completely quench any
motivation for construction and launch of an Oumuamua-like probe. The absence
of any such motivation attests that Oumuamua is not an alien creation. The
existence of large space telescopes has important implications for a range of
topics that include interstellar space travel, the zoo hypothesis, METI, and
UFOs.
