As if Creation could ever be divided and owned

Hello everybody

He considered other potential routes. First to the United States by way of Canada,but ruled it out when he learned the two countries share immigration information. A flight to Jamaica or the Bahamas since neither required visas of Colombians. Or by boat to Panama through the Darién Gap and San Blas Islands, by bus and train the rest of the way north. 'The more he stared at those borders on maps, the more absurd it seemed that outsiders succeeded in declaring possession of these lands with national lines, as if Creation could ever be divided and owned.'

Would you please explain to me what the writer is trying to say by 'The more he stared at those borders on maps, the more absurd it seemed that outsiders succeeded in declaring possession of these lands with national lines, as if Creation could ever be divided and owned.'

Why is Creation capitalized?

Thanks so much for your help.
