It is likely that there are other life forms in the universe
When talking about space, it is impossible not to think about aliens. These otherworldly creatures are a staple of many Science Fiction novels, and although no evidence has been found of their existence yet, experts believe that there are likely other forms of life. Just perhaps not in the way you would expect them to be.
After all, the universe is so vast that it is highly possible that one galaxy amongst the many out there can recreate an ecosystem with the ability to sustain life. Of course, they would probably not be green humanoid creatures, but it is not a stretch to believe they could exist in some form.
