Because existence is completely different (existence, وجود (than life (life, حياة .(This is not philosophy, but teaching.

The Lord is Eternal, so His existence was, is, and will be. Existence is nothing else than occupying a part from the space. It can be physical space and non-material space. We can occupy a room, a country, an office, and we can occupy spaces of thoughts, theories and principles. But every existence is a drop from the infinite space of the Eternal Allah (SWT). There are planets, animals, plants, grass, trees and anything else that occupy a piece from the space. Here you are the few lines that are sold to tourists in bazaars in the middle east, what is woven into carpets or calligraphically depicted as a holy caption:

Allah. There is no god but He,-the Living, the Self-subsisting, Eternal. No slumber can seize Him nor sleep. His are all things in the heavens and on earth. Who is there can intercede in His presence except as He permitteth? He knoweth what (appeareth to His creatures as) before or after or behind them. Nor shall they compass aught of His knowledge except as He willeth. His Throne doth extend over the heavens and the earth, and He feeleth no fatigue in guarding and preserving them for He is the Most High, the Supreme (in glory). (Quran 2:255)

These are the throne verses. Those express the infinite space of Allah from which He gives to whom He wills.
Maintaining the space, i.e. existence is a problem. It needs energy input, maintenance of the system, heating, cooling, learning, following social norms, etc. When I enter into a room where I am alone, it becomes my space. If you enter there too, you're going to disturb my space. In order not to disturb each other, we need to do something. We can talk, listen to lectures, watch movies, so we need something that makes our common existence bearable. A marriage is also like that. Two existences, i.e. two parties push together the spaces they occupy. This can be successful or unsuccessful.

Life is completely different. Life is life, and it is even there when there is no existence, i.e. space occupation. Simply because life cannot die. If it'd die, it wouldn't be called life. Thus, the term death of life is absurd, according to the Islamic perception it is impossible. The biblical Judaism considers the same way! Because life is nothing but joy, happiness that we feel when we can contribute with something to the existence! I don’t mean animal pleasure when eating a good portion of grass or the beauty of mating causes instinctive pleasure, but human blissfulness that doesn't come from instincts. The animal has no consciousness, so has no free will either. The instincts are behind its decisions. If its instincts inspire it for good, it eats, multiplies, if for bad, then it starves, does not multiply, or just becomes a prey. If human life is about that, he/she is no different from an animal. If, on the other hand, he/she makes decisions that contribute to the Creator's beautifying, improving plan, it is a worth-for-human life and brings joy. Life is the opposite of existence. In existence, we look what we should get in order to maintain our being and the space we occupy. Regarding life, we look what we can do to contribute to God's plan or the prosperity of His creatures! That's why we live! This is our driving force, our motivation, our joy. In Judaism, the space for this is the earthly existence. So, the joy of life of religious Jews is bound to the earthly existence. They have an afterlife theory, there is a separation of soul and body according to their teachings, too. Moreover, the path of the soul in the afterlife is the same in Judaism as in Islam. But their rabbis do not focus on the afterlife, but emphasize their earthly contributions. Now I don’t want to hear the bullshit about the chosen nation who are sucking the blood of people, and others. There are examples of everything, but now I deal with the doctrines of biblical Judaism, which teaches not the pleasures and desires of the world, but the positive contribution of the Jews to the life of the world, which is joy, happiness and that's what life means. That's what Lekhaim is all about!
In this sense, the Nazi “living space” (Lebensraum) theory is completely incomprehensible because life and space are contradictory concepts because of the above derivation.
It is this religious Jewish perception that makes them able to live their faith anywhere, since neither their existence nor their contribution to existence requires a country. This has helped them to survive in the past two thousand years. All this is completely different from Zionism, which is a principle bound to a physical space. But Zionism is inconsistent with the teachings of biblical Judaism and is mostly linked to atheist Jews. I said mostly… because there are also religious people who support it, but from here this story is complicated. Let's remain at biblical Judaism.

At the same time, the teachings of Islam are not consistent with Palestinian statehood either. Despite the establishment of religious-based movements (Hamas, Hezbollah), they cannot use the word of Allah to impose boundaries, physical spaces! One God cannot have two positions on the issue of territorial existence. Therefore, there is none. God does not impose territorial boundaries. God sets principles of coexistence. But not so, that for the Jews this and for the Arabs that! There is no such differentiation! الناس أيها يا O, people! ادم بني يا O, children of Adam etc.!
If the question arises that blowing up innocent people at a bus stop is a sin, then yes, it is! Is launching missiles to innocent citizens of cities considered a sin? Yes, it is sin! Just as it is a sin to torture innocent children, cut off olive trees, isolate water, infrastructure from residents, etc.! Sin is there in all sides. And no matter Judaism or Islam the main sin is: every side is fighting for existence, not for life! To maintain their existence makes their days bitter. They would live if they contributed to the each other’s existence and joy! Please don’t escape into the historical grievances, to Nakba Day and the horrors on both sides. Almost the third generation is born, consciously turning them against each other. This is existence, but not life. Once the day comes when not the existence of the parties but their lives will be discussed, the One God will be happy, because this time His qualities will permeate people. Because, returning back to the previous example about the spouses who push their spaces together, when does that lead to happiness, i.e. life? When will the two spaces, the two existence, become livable? When they both experience their joy in contributing to the other’s existence. If they discuss their things meaningfully, cause each other experiences, one supports the other in professional development, etc. To do this, they have to sacrifice part of their own existence, but it is worth. Joy will come only that way!
If we read the throne verses better, God is Eternal, so the privilege of existence belongs to Him. But He is the Life, too! He gives the life. Where does He give life from? From His own Live attributes! We have seen before that He breathes soul into the inanimate matter. The soul is charged with His 99 attributes, which are indicated by His names! The soul is present from the moment of conception. In the book of Psalms, David miraculously states in verse 27:10:
International Standard Version:
“Though my father and my mother abandoned me, the LORD gathers me up.”
This thought also meets the words of the Quran. So, leaving mother and father, the Lord brings man forth as a new creature. It also expresses that the soul is not a product of the body, but comes from the Lord! In Judaism, we have seen what the meaning of life is. Finding prosperity on earth, harmony, contribution, and the joy that comes from that all. In Islam, this is complemented by a strong afterlife consciousness. So, similarly with the teachings of Judaism, earthly prosperity is there, but the attention to the afterlife gets importance as well. Because Allah has not given without limitations the spaces necessary for existence. These are loans that need to be reckoned for. Man can thrive with them, but let there be existence, physical endowment, wealth, all things have been put to use for only a transitional period. The way those are used determines our human quality and the outcome of the afterlife evaluation, i.e. our worldly and afterlife prosperity:

Allah hath purchased of the believers their persons and their goods; for theirs (in return) is the garden (of Paradise): they fight in His cause, and slay and are slain: a promise binding on Him in truth, through the Law, the Gospel, and the Qur'an: and who is more faithful to his covenant than Allah. then rejoice in the bargain which ye have concluded: that is the achievement supreme. (Quran 9:111)
