How Foolish We Seem

Knowing that Gulliver's Travels is a giant satire helps in figuring out Swift's intentions of relating the customs of Lilliput. Everything Gulliver conceives seems to be a joke. At the same time, however, the fact that Gulliver is looking at all these ridiculous customs makes me think about what would happen if we were the Lilliputians.
How would a complete stranger who lives in a world with completely different customs view our world? I think the Lilliputian burial services is ridiculous: "They bury their dead with their heads directly downward, because they hold an opinion, that in eleven thousand moons they are all to rise again; in which period the earth (which they conceive to be flat) will turn upside down, and by this means they shall, at their resurrection, be found ready standing on their feet." (Swift 40,41) In that light, how would our burial customs seem to an outsider? Is putting people in boxes underground ridiculous? What are the origins of burying people? Is it something to do with resurrection as well?
Another weird Lilliput custom is the parent-son relationship. The parents don't do the raising at all and only see their offspring a couple of times a year. Is it weird that our parents raise us? How would it be different?
