1. Judgment is Hard
Judgment is the act of picking which of a set of objects or persons is good or the best.
Supposing there are three laptops in the market from Factory A, Factory B and Factory C. Intel (a computer company) must have done a good job in teaching the three factories and the laptops are all good (last five years, all come with Windows).
One might indeed be better than the other: Factory B might not have paid their staff wages properly and in fact Factory C might have suggested some things to Intel, the source of computers on earth.
This information about the three factories would most likely not be known by the buyers.
You might have seen a young person pick another young person for marriage. Then after some years in marriage, they decide to get a divorce.
Note: Two proofs is usually enough.
Electricity shocks a person if touched. And if there is too much exposure to electricity, there could be death.
Electricity is much needed on Earth to run machines.
So therefore, something that is good could also have bad properties.
This earth was created to test people, objects and ideas before taking them to heaven.
None of us can build an earth.
