How long can humans live on the earth? Look at the answer dsfdsfdsdeygyeyguewyeewejoieufygegfdffgf.

At present, when human energy comes directly or indirectly from the sun, but the sun is not infinite heat and light, it will be closed in 1 day (in a few billion years), and the temperature of the earth will drop to-80 to-0/30 degrees, which is harmful to human survival.

This technology shows that technology has primitive human life, but because of the low survival rate, when the solar energy is exhausted and the interstellar immigrants leave the cradle of the earth, there is no technology. Now we can also see that because of the earth-shaking changes in science and the earth, "science and technology are the primary productive forces" in our lives.

This is just my personal opinion. Please forgive me if it is broken, hehe.
