Gợi ý trả lời :

Option 1: Yes

I believe there is life on other planets because the universe is extremely large. There are billions of galaxies and stars, so Earth cannot be the only place with life. Maybe they are micro-creatures or very different from us.

Option 2: No

I don't think so. Scientists have explored Mars and the Moon but found no aliens. Life needs water and air, and Earth seems to be the only lucky planet to have them.

There are some important conditions a planet must have to support human life. Firstly, the most important condition is water. The planet needs to have enough liquid water for drinking and growing plants. Secondly, it must have an atmosphere with enough oxygen for us to breathe. If there is no air, humans cannot survive. Thirdly, the temperature must be suitable. It should not be too hot or too cold. Finally, the planet needs to have strong enough gravity to hold the atmosphere.
