If the earth is destroyed, to which planet might humans migrate?

If the earth is completely destroyed, the moon will no longer exist, because the moon is a satellite of the earth and will definitely float away. Without the earth in the solar system, the magnetic field will definitely change, and other planets, such as Mars, may also change their positions. So it is impossible to predict the destruction of the earth, and it is still suitable for the remaining human beings to live there.

At present, all space migration plans are based on the earth. With the current technology, it is basically impossible to realize the space migration plan in the next 50 years.

For our future, for our future generations, I hope everyone will protect and cherish nature and the earth, the only blue planet with life found at present ~ ~ ~
