Seeing that the Second Coming hasn’t arrived, it suggests that the word “generation” has a different meaning in this context. Nice try, fella.
Were you there? How would you know? Joh 14:2&3 & 1Th 4:17 say that he takes the bride to heaven, not earth. He would have showed up, and then left. Maybe the Romans would have written about it. Wait, no, they didn't even write about all of the dead coming to life in Mat 27:52. Wait, didn't they have CNN back then? Maybe we could check the video logs. Nope! Lol. I guess we should ask Josephus. ;) :)
Yes, it seems to be a spiritual generation. Besides, we were already in historic times during the first century. Surely it would be noted somewhere by someone if all those people disappeared.
