7 Reasons Why Life Might Exist on Other Planets
Here are seven reasons why it is worthy to believe that life could exist on other planets in the universe, waiting for us to find it.
1. Theory of evolution
2. The mystery of the origin of life on Earth
3. Variety and persistence of life on Earth
4. Extremophiles on Earth
5. A rapidly increasing number of Earth-like planets
6. Building blocks of life on other planets
7. Oceans and lakes are very common in our solar system

Content: Why would not the same thing happen on another planet in our solar system, or even in another star system? 4. Extremophiles on Earth
Extremophiles are organisms that can survive in the extreme conditions of cold, heat, exposure to toxic chemicals, and even in the vacuum. These creatures can live in subglacial lakes in the Arctic or in the hot volcanic vents. Tardigrades, amazing tiny organisms, can survive even in the vacuum. Thus we see that life can exist in such a hostile environment on Earth, therefore it can also exist on planets radically different from Earth. 5. A rapidly increasing number of Earth-like planets
In the last decade, a great number of planets outside the solar system were discovered, many of which are gas giants like Jupiter. However, technological advantages have allowed scientists to find smaller, solid planets like Earth. Moreover, some of them are in the so-called “habitable zone”, i.e. at such a distance from their star that they approach the terrestrial temperatures.
