Your assertion has been disproven hereon multiple times.
Very clear documentation can be found many hundreds of years back and some researchers convincingly trace it back to the first century church.
Yet again, you are WRONG.
What are your speculations about the UFO phenomena, then?
I assure you it will be shocking enough that the Scriptural prophecy about men’s hearts failing them for fear will come true many thousands of times shortly after disclosure leaps on the world stage dramatically and overtly.
Kindly post the evidence by which "some researchers" trace the rapture/tribulation doctrine (aka Dispensationalism) back to the first century church.
The truth is that over two millennia of Christian history neither the Catholic nor the Orthodox Church has ever taught about any "rapture". It is simply not part of the traditional Christian faith.
And it's not just us Mary-worshippers: Martin Luther never heard of it. Calvin, Zwingli, and Henry VIII never heard of it. John Wesley might have heard of it, but he never taught it. So where did this strange doctrine come from?
it came from the USA by way of John Nelson Darby, a strident anti-Catholic Irish Anglican preacher and a renegade member of the Plymouth Brethren.
The Rapture seems to have been invented by a British religious figure named John Nelson Darby (1800-1882). He was ordained in the Church of Ireland and worked there to convert Catholics away from their folly. He was extremely pessimistic about what he saw as the state of the world and the state of the Church. He eventually left it, joining a dissident group called the Plymouth Brethren of which he soon became a prominent leader.So who does teach the Rapture? Not mainstream Christians. The Catholics and Greek Orthodox don't, as I said. But the Episcopals and Anglicans don't, either. The Lutherans don't. The Methodists and Presbyterians don't. Even most Baptists (those in union with Nashville) don't. The only denoms that push the whole Rapture thing are the Big Evangelicals (e.g the Assemblies of God), the 'non-denominational" Evangelical superchurches, and outfits like Ruckman and Bob Jones.About 1830, he began teaching that Jesus’ coming at the end of time would be preceded by a “rapture of the saints.” Some members of his own Brethren community objected that this was not biblically founded, but Darby dismissed any criticism. It had, he claimed, been revealed to him by God.

[S]cholars have suggested several possible influences on his Rapture views. In 1830, in Port Glasgow, Scotland, a 15-year-old girl, Margaret MacDonald, a follower of a charismatic Scottish preacher, Edward Irving, attended a healing service at which she saw a vision of a two-stage return of Christ. Darby adopted and expanded her vision.
Another suggestion traces the influence to a Jesuit priest, Manuel Lacunza (1731-1801), who was born in Chile but came to Italy in 1767 where he would spend the rest of his life. Posing as a converted Jew (under the pseudonym Juan Josafat Ben Ezra), he wrote, in Spanish, a large apocalyptic work entitled The Coming of the Messiah in Glory and Majesty. The book appeared first in 1811, 10 years after his death. In 1827, it was translated into English by none other than Edward Irving, an acquaintance of and possible influence on Darby. Given Darby’s hatred of Catholics, this possible influence adds an ironic touch! Source
So, with all due respect, I think I'll stick with the belief in the Second Coming as taught by our Lord, the Catholic Church, and the entire Christian faith up until the 19th Century. As entertaining as the whole "last days" thing is (I have a huge collection of Rapture/Trib propaganda, btw), it ain't the Truth. If I want to read 19th Century science fiction I'll stick with Jules Verne.
