*4.2.1 City and a need for existences*

In order to survive, plants need air and water, as well as heat and light. Can they meet their own needs? People's needs are endless. Fortunately, from all our essential needs, from the beginning of our life from the womb to death, someone is able to fulfill them and who chooses to do so. When human beings come to this world, we find everything prepared to satisfy all the needs of the senses, mental and spiritual. Everything is contingent, because it is as possible that they exist or do not exist. Anything can exist anytime, anywhere, in any form, and with any character. Nothing and no one has a role in determining the manner, time, and place in which it occurs, its character and characteristics. Therefore, there must be a power to choose between the existence of a thing and its nonexistence, which confers unique characteristics on it.
