I answered the question. I will repeat the answer. Why do you assume the we is specifically him and not the collective we of all Christians at the time of his coming. Keep in mind that at times English is ambiguous when using personal pronouns. You will have to go to the original language to verify who "we" is.
Well, that's really absurd because there's a 'we', which stands for the believers that are alive during Christ's coming and there's a 'them' which stands for believers that are dead during Christ's coming. Paul should have counted himself collectively amongst 'them' that would be raised and be caught up with those that are alive.
It gets worse for your theology because initially, Paul counted himself amongst the dead who will be raised and be caught up together with his listeners at Corinth in their life time and not some 2000 years after:
2 Cor 4:
11For we who are alive are always being given over to death for Jesus’ sake, so that his life may also be revealed in our mortal body.
12So then, death is at work in us, but life is at work in you.
13It is written: “I believed; therefore I have spoken.”
b Since we have that same spirit of
c faith, we also believe and therefore speak,
14because we know that the one who raised the Lord Jesus from the dead will also raise us with Jesus and present us with you to himself. 15All this is for your benefit, so that the grace that is reaching more and more people may cause thanksgiving to overflow to the glory of God.
Paul did not make a mistake twice, he knows what he is teaching which is miles apart from your understanding. Paul is not teaching a future resurrection but a continuous one. and of course he has a question for you:
1 Cor 15:
29 Now if there is no resurrection, what will those do who are baptized for the dead? If the dead are not raised at all, why are people baptized for them?
Note; Paul is not asking "...if
there will be no resurrection, what will they do...".
With your false theology, you'll never ever, have an answer to this question.
