Where will human migration go in the future? Are there any planets like the earth?

Mars. A day on earth is 23:56, and a day on Mars is 24:37. They have almost the same day and night. The earth tilts 23 degrees 17 and Mars 25 degrees 1 1. So the four seasons are the same, except that Mars is not suitable for human habitation, and the temperature is between-140 ~-60. Therefore, scientists set up 300 balloons made of reflective materials to raise the temperature of Mars to. Then we must change the atmosphere of Mars. In short, it may take thousands of years to complete these tasks.
