You've been given the power to remove anyone, who was alive before you were born, from the timeline. How do you use this power without inadvertently making it so you were never born?
It's been discussed here much better than I could, but I concur with, you pretty much can't.
The slightest change would cause ripple effects that would affect almost everything.
Everyone always gravitates to the big names... Hitler, Trump, Elmo.. But even the most possible mundane person, such as an Inuit baby born to parents in the remotest part of the Arctic 200 years ago, would be enough to cause changes that could easily keep you from being born.
I mean removing someone who was born in between when your parents got together and when you were born would be fairlu safe. The odds that some random baby's absence in those months/years that they're together but not pregnant is not impossible, but pretty slim.
If you can pick any time and place pick a random person in bumfuck middle of no where in Mongolia 1 day before you were born or even when your parents sexed that led to you would be fine. Unless you live in Mongolia
