The problem with Camping’s prediction is that it was diametrically opposed to what scripture says. Scripture clearly teaches that we can know the approximate time, but nobody will know the exact day.
Your comment is diametrically opposed to what scripture says as well. It warns us not to believe anyone who says he has “secretly” come and can be found somewhere. It says that when He comes, everyone will know it. Everyone.
Think of the movie “Independence Day”, only much more so.
Welcome to EARTH!
Actually, I'm more reminded of Groundhog Day.
