I have been corrected twice in the sentence
I was not alive, at that point in time.
We were having a discussion involving life in the 1980s, and at some point I said I was not alive so I would not know. Someone corrected me saying the correct way of saying it is I was not born at point in time.
To me it seems perfectly grammatically correct to say I was not alive, for it is a true statement. It seems to me that saying I was not alive means that I was dead before, which then turns it into a philosophical argument.
I was not alive at the point in time.
This seems to be equally valid with I was not born or I did not exist.
Is it just context or it is just the way we say it just because? Am I correct to keep saying I was not alive?
