If there is any life on other planets, it will be put in a drawer, when their purpose has passed.
Psalm 102 says: "Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands. They shall perish, but thou shalt endure: yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed: but thou art the same, and thy years shall have no end."
...and in Revelation, "And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind. And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places."
I just picture The Lord rolling up the heavens, putting them in a drawer, and getting out The New Heavens and The New Earth.
