There are other structures, on other planets, even on those that disintegrate.
Counting, chemistry, mathematics, physics and harmony will be different on each planet, though all these elements will be recognised as other subjects. Other than those we can understand, which are both formal and both informal for all users.

Now, the identity and history of the world is one of the very good things which can create a lot of respect for human beings. It tells us how we can survive the extinction and how long we will be able to own it.
