Hi, the best way to answer the questions you have asked is to examine the history books or a place where you can find these answers. First off do you read the Bible? What religion do you associate with? The answer to your question should come from your religion.
If the answers from your religion does not satisfy you, next place would be to try an independent Bible study to find your answers on your own. The question should be clarified, what does the question relate to, the End of the World or what? In considering steps of Doomsday Destruction what happens first, second, and third, Matthew 24:14. Asking a general question: Will people be destroyed period, 2 Thessalonians 1:6-8. Next ask: Will the earth remain, or will it be destroyed as in gone forever, Isaiah 45:18. The best place to start is to go online and asked if humans will be destroyed by God, lots of people have asked the same question you will surely find the answer and, in the Bible, too. Then ask the next question the same way online: Will God destroy the earth? You will surely find what you are looking for and with satisfactory answers too. Peace.
