Is everything virtual? As for example, we calibrate the day as per the rotation of our earth and that too with the concept of calculation of time which is only made by us. When we send space craft we send it calculating the relative velocity and not the real velocity from our planet to the other which is obviously not a static object. There may be so many examples in this issue. What do you say?

Well, we have to have a measurement system so we can define it anyway we want.The earth didn't evolve with clocks built into mountains and meter sticks growing out of the ground so we're pretty much free to measure as we choose.

Oh yes the earth evolved with clocks!
The rotation on a daily basis is exactly the same as the previous.
The seasons occur at a given time, measured exactly as all previous occurrences.
The number of days completed till the next cycle is exactly the same as the previous complete cycle. . . .and the beat goes on
