Some ideas are:

You branch off into another timeline and your actions make no difference to the previous timeline
You’ve already taken said actions but just didn’t know about it so nothing changes
Actions taken can have an effect (so you could suddenly erase yourself if you killed your parents)
Only “nexus” or fixed events really matter, the timeline will sort itself out for minor changes
something else entirely

Logically speaking it's the only way time travel can be done, and for bonus points physics wouldn't have a problem with it.

Any Back to the Future shenanigans is just creating alternate realities, which may or may not instantly destroy the original.
