Cause and effect in Buddhism, but where do we come from?

The basis of Buddhism about cause and effect is the theory of origin.

Origin "means" all laws begin with cause ". Simply put, the birth of all things or phenomena is the relationship and condition of mutual (relative) treatment. Without this relationship and condition, nothing or phenomenon can be born. Generally speaking, Hetu and Paccaya are relations and conditions. The Buddha once defined "origin" as follows: where there is, there is, where there is this life, there is an afterlife; If there is nothing here, there is nothing there; If there is nothing here, there is nothing there. These four sentences mean coexistence at the same time or at different times.

People are entities, but the birth of a person depends at least on your parents. Acquaintance is fate, love is fate, and having children is fate. Only fate can get to know each other and love each other (this is because) can have children. Hehe, this is the result.
