It's kind of a commentary on how humans will create reasons for things to exist, even if they are not intended to exist.
Like if a shadow was pointing the wrong way.
We'd have a reason.

Well the reason is that proximity to gravitational forces affects how time flows. Like you can just go buy two atomic clocks, put one at the base of a mountain, climb the mountain, hang out for awhile, come back down and observe the difference.
So you can say that isn't time dilation or its not gravity or whatever, you do you, but its an observable thing that happens. And our best reasoning for why it happens is gravity and speed. So much so that we can predict those differences and those predictions are accurate. I mean that's how your GPS works.
It's been exhaustively tested and observed.
And let's be super duper clear--let's say hypothetically you're correct and its not due to time dilation, that part isn't the part that matters. The part that matters is that it happens and allows us to provide a predictable model for how the world works that we can do useful things with, like having GPS satellites that can tell you where you are and where you're going.
