Paradoxical, isn't it?
yup!
Depends on whether you believe in a Static Line of Time or Dynamic Line of Time, or whatever their correct terminologies are.
For a DLoT, what you say is true, or is for at least one of its theories (the other is that the universe can spontaneously explode from a paradox being created, I believe, but the more rational argument is that alterniverses are created instead).
For a SLoT, all points of time are already accounted for and predetermined, and set in stone (AKA, cannot be changed or altered in any way). If I recall, SLoT argues that all points of time are occurring simultaneously and there is no true "present" as all points of time are essentially "present", and "past" and "future" are entirely personal perspectives rather than any universal points in time, but I forget. Anyhow, SLoT dictates that what will happen in the future is already accounted for in the past. What happens in a certain point of time, always happened, always will happen, and never did not happen. In other words, if you created a time machine and traveled 3000 years in the past, you would not be changing the past, as you have always appeared in 1000 BC, and have never not been there.
According to SLoT, the grandfather paradox is impossible, because the past can't be changed, thus if there was ever an attempt to destroy humanity in the past, there was always an attempt to destroy humanity in the past, and our being here today is evidence that it did not succeed and never will.
