"Left Behind" a series of fiction books, written by Tim LaHaye and Jerry B. Jenkins which made the New York Times Fiction best seller list and made a lot of money for the authors. It was then made into a bunch of fiction movies, making more money for this fiction account of end times.
So here is my challenge to you, Samual, put the word Rapture into the search engine for any reputable Bible translation, from KJV to ESV and more. Try Biblegateway, as there are many versions on there. You will not find the word "rapture" in any translation.
Then there is 1 Thess. 4:17 which I have dealt with over and over and over!
"Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord." 1 Thess 4:17 ESV
"ἔπειτα ἡμεῖς οἱ ζῶντες οἱ περιλειπόμενοι ἅμα σὺν αὐτοῖς ἁρπαγησόμεθα ἐν νεφέλαις εἰς ἀπάντησιν τοῦ κυρίου εἰς ἀέρα· καὶ οὕτως πάντοτε σὺν κυρίῳ ἐσόμεθα." 1 Thess. 4:17 Greek
The words "to meet" are ἀπάντησιν or apantesin in Greek. This word is only used three times in the New Testament, always when people meet someone AND RETURN. In other words, we are going to meet Jesus and return to earth with him. That is the Second Coming of Jesus Christ.
"so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him." Hebrews 9:28
No rapture, not in the Bible. No one left behind, because we are returning with Jesus!
But I do think we need to have our lives in order and be following Christ before he returns. So instead of worrying about nonsense end times stuff, focus on living a Christ-like life, and sharing the gospel.
