One of the reasons given by non-believers of alien is the lack of water in outer space. Critics believe that as water is the base of life, it is essential for water to exist or there is no way alien life could exist.
The non-believers need to come up with another reason because astronomers have discovered a gigantic, 12-billion-year-old cloud in outer space that is harboring 140 trillion times more water than all of Earth's oceans combined. Water in that amount could wipe out any fears we have about water shortage on Earth in the future.
Although water has been found before in outer space, this is without question the largest quantity we have ever found. So there we have it; there’s a lot of water in space. And I do mean a lot!
