Life on Other Planets
The question of how life originated has been a sour point for many scholars. Many have presented their cases through scientific research, key among them is the theory of evolution by Charles Darwin. In his theory, it is believed that all life evolved from one form to another, and the conditions present played a big role in the whole process. Organisms multiply giving rise to more of its species and with time, change their characteristics allowing them to adapt and survive.
Given the realities known concerning our solar system, it is very hard to ignore the possibility of life in other planets. Habitable planets have been discovered by scientists across the galaxy. Some of these planets are similar to earth with the presence of water and rocky surfaces. They are also in a habitable zone, orbiting close to a star in their various solar systems, thus ensuring favorable conditions to sustain life.
Closer to home, Mars is believed to possess favorable conditions that can support life, leading to companies such as Space X to formulate plans to colonize it (Vago, 2019). With all this evidence and facts, I believe that there is a high probability that life exists on other planets in one form or another.
Alien life on other planets will be highly adapted to the conditions present. The atmosphere of the planets will determine where the species will live. If habitable, the living organisms will live on the surfaces while if not, they will be forced to live underground. The gravity of the planets will also affect these life forms especially regarding their means of locomotion (Ramirez, 2018).
Given the vast expanse of the universe, it is hard not to believe in the existence of sentient life on other planets. I believe that in one or more planets, life exists in one form or another.
