Scientists have concluded that there is at least the following conditions for the existence of life on the earth: first, the existence of liquid water; the second is to maintain a certain distance from the heat source to produce a suitable stable temperature range; in other parts of the universe, this The simultaneous appearance of two conditions is almost impossible, so it is impossible for other planets to have the same life as on Earth. Which of the following can best refute the above points:. ['Liquid water and a stable temperature range are not the only conditions for life.', 'The scientific and technological level of human observation of the universe has not reached a level high enough for humans to understand the entire universe.', 'Scientists have found liquid water on a planet for a long time.', 'Scientists predict that the environmental adaptability of cosmic creatures may be stronger than humans.']
