Hello, the Great Tribulation happened during the modern era so it cannot return to a time of the past. The world we live in today is full of modern technology in every field, but we still struggle with clean water and decent housing. The world that we can look forwards to in the future will have resolved these problems so they no longer exist.
Isaiah 65:20-22
Easy-to-Read Version
20 In that city there will never be a baby who lives only a few days,
and every older person will live for a long, long time.
A person who lives 100 years will be called young.
And whoever doesn’t live that long will be considered cursed.
21 “In that city whoever builds a house will live there;
whoever plants a vineyard will eat the grapes from that garden.
22 Never again will one person build a house
and another person live there.
Never again will one person plant a garden
and another eat the fruit from it.
My people will live as long as the trees.
My chosen people will get full use of whatever they make.
