At the end of the tribulation period Christ will rule on Earth for 1,000 years. Of course the Earth was here, is here, and will be here in the future. Learn something.
True, but it doesn’t mean there won’t be some nuclear damage God will have to miraculously clean up first! The rapture (calling away) will leave a godless planet, which anything can happen during Armegeddon:

Those who do not understand the rapture need to know that ‘harpazo’ in Scripture means ‘rapture’ aka ‘catching away’. If you read the article on Harpazo (link), you will know that parable of Ten Virgins among other Scriptures are to help Christian understand this.
