Going through the Tribulation would ensure that believers are going to be destroyed along with the evil ones between the judgments of God and the mark of the beast thing.
Unless you hold that God's judgments are going to hit only unbelievers but I don't see anything in Scripture that supports that.
Besides, I don't see anything indicating the Rapture is going to be secret. You don't think people are not going to notice millions of people missing?
You are wrong. Christ destroys the earth upon His return.
2 Peter 3:10-11
10 But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up.[b] 11 Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness, 12 looking for and hastening the coming of the day of God, because of which the heavens will be dissolved, being on fire, and the elements will melt with fervent heat?
