Answer: The term earth refers to the spiritual foundation. The land of Israel is not Palestine or the State of Israel, but a spiritual quality in which people are in a state of mutual love.
The Torah describes that when people came to Mount Sinai, when hatred arose between them, they were given a condition: either you must unite or here will be your burial place.
My Response: Unification is the main law of nature, and we must realize it. The thing is that after the Big Bang, there was a breakage of our desire into a huge number of desires, and we must unite them.
All nature is striving to its unification only very slowly, gradually, according to its laws. We are required to unite between ourselves on our level, on the human level, i.e., on the highest level of nature.
There the problem arises: we are not aware of it, do not understand it, and do not want to implement it. But we still must complete this task either by goodwill or, as they say, by the stick, to happiness.
