Are human beings alien immigrants?

My idea tells you that you may not agree that the origin of life of the first organism should meet the following conditions: first, temperature (adaptation), second, water, third, air and fourth, sunlight. With these conditions, biological bacteria and biological bacteria will evolve with the changes of sunlight, temperature and air. In fact, we can see this phenomenon now (algae and aquatic plants will be born for a long time in the newly built pool). As for alien immigrants, it depends on the scientific development of human beings and the future energy development of the earth. If energy is over-exploited, immigrants are not allowed without recycling.
