In 70,000 BC, there were only about 2,000 human beings left oh.

If you were standing at the equator of the earth when you were 6 years old,
and all 8-year-old men and women oh, every 1 sed, a man and a woman must pass in front of you,
May I ask how old are the men and women who pass by when you are 300 years old?

Earth' s civilization in 7017 AD reach the sed-level stelr civilization,
If humans do not bee extinct within 3 million years,
Then in the 3 million years of the earth' s Gregorian dar, human beings will find a p suitable for humaence,
In 1.5 billion years of the earth' s Gregorian dar,
The luminosity of the sun will increase a lot, causing the earth' s climate to overheat,
Threatening the survival of multicellur anisms, the earth' s enviro will be Martianized,
At the time of 3.3 billion years of the earth' s Gregorian dar,
Mercury may hit Venus, causing the entire sor system to face a major colpse,
At 4 billion years of the earth' s Gregorian era,
The Andromeda Gaxy, 220,000 light-years in diameter, and the Milky Way, 180,000 light-years in diameter, will collide,
