What if time doesn't exist outside of a black hole's event horizon?

They did a a real experiment with two atomic clock. One on earth one in space. The one in space did run slower.
So yes you make a good scientific point.

Well, time can also be thought of as a measure of change, or entropy. Our current standards of timekeeping, the atomic clocks, measure a second by counting decay events in radioactive Cesium or other elements. We're Humans non-existent, the atoms of these radioactive elements would still continue to decay at their normal rates, seeking a stable state. (Yes, the argument can be made that some of these elements are man-made, and would exist to decay if we weren't here, but others would)
Entropy would still exist, stars would still be created and die, and eventually protons would decay. This would occur in the same linear fashion if we weren't here. So while the measurements we use to define units of time are arbitrary, the overall existence of time is fully independent of us.

you would be incorrect because mass does effect time. time passes slower next to a big mass such as say the pyramids compared to someone 1/4 of a mile away. it's not pyramid magic; its the mass/gravity thing.

Really? How fascinating! So you could set two synchronized clocks out, one at the pyramids and the other 1/4 mile away and they would actually record different increments of time? One would be behind the other?

yes! that was even a thing on a show about relativity. they did exactly that as a gedanken; one of several examples.

That's due mainly to the effects of adrenaline. It increases awareness and sensory perception, as well as increasing neural activity. Therefore we process the moment faster in our minds, so the time frame seems slower than normal.
