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: 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. Given the great number of planets outside our solar system, there is a probability that there are forms of life on one of them. 6. Building blocks of life on other planets
It is believed that life on Earth began from chemical reactions that led to the formation of cell membranes and DNA. However, these chemical reactions could have begun from complex organic compounds, such as proteins, nucleic acids, etc. There is evidence that such substances already exist on other planets.
