Plagiarism w.r.t. Horizon Backstory

For example, @MrVideoFreak_YT, they pointed out that

1. Cooper promises Murph that he'll return,

2. that humanity is at stake if Cooper's mission doesn't execute,

3. Cooper was betrayed by someone else on the mission, and

4. Time dilation forces Cooper to miss his child's life

Also (I'm not sure if I realized this or if this is from what the other people had said), Cooper needed to go to the black hole to get the thing that would save humanity, which is exactly the same as what happens with Horizon. Other things may be similar that I haven't stated here.

I really didn't need to spell this out for you; if you had seen the movie, some or all of the similarities would have been in-plain-sight, which makes me question if you actually had seen the movie at all.
