Quote from Wikipedia....
Pre-tribulation rapture theology originated in the eighteenth century, with the Puritan preachers Increase and Cotton Mather, and was popularized extensively in the 1830s by John Nelson Darby[12][13] and the Plymouth Brethren,[14] and further in the United States by the wide circulation of the Scofield Reference Bible in the early 20th century

As you can see the concept of a rapture is rather recent in Christian Theology. This fact alone should generate some skepticism amongst the Christians. ​

Maybe we could just point a very large cannon skyward and offer christains a free ride to heaven.

Remember that episode from “Six Feet Under”?!
