There is another planet earth with another world above in the heavens that is hidden but, one day it will be revealed on the Last day at the Day of Judgment (2 Timothy 4:1-5)..
“While we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal; but [THE THINGS WHICH ARE NOT SEEN ARE ETERNAL]” (2 Corinthians 4:18).
Unfortunately, many people fail to realize that at the time of creation worlds were created; not just this world where we are now.
“God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, [BY WHOM ALSO HE MADE THE WORLDS]” (Hebrews 1:1–2).
Jesus is in the heavens where there is already NEW HEAVENS AND A NEW EARTH where there is the NEW JERUSALEM. In the Book of Revelation John said:
“[AND I SAW A GREAT WHITE THRONE, AND HIM THAT SAT ON IT, FROM WHOSE FACE THE EARTH AND THE HEAVEN FLED AWAY; AND THERE WAS FOUND NO PLACE FOR THEM]” (Revelation 20:11).
“And I saw a [NEW HEAVEN AND A NEW EARTH]: [FOR THE FIRST HEAVEN AND THE FIRST EARTH WERE PASSED AWAY]; and there was no more sea. And I John saw the holy city, [NEW JERUSALEM], [COMING DOWN FROM GOD OUT OF HEAVEN], prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God” (Revelation 21:1-3).
