Every living thing must reproduce to prove that they are alive

True.

Explanation:

Every living being needs to be born, grow, reproduce and die. For this reason, we can state that, generally speaking, every living being must reproduce to prove that he is alive.

From the point of view of evolution, in addition to being born and growing, living beings also adapt for their survival and may even create new species. In the aspect of reproduction, we are talking about the ability to create progenitor-like offspring, which Living Beings realize in two ways: sexual, through the sex of the progenitors, that is, through gametes, reproductive cells, in the case of sexed organisms; asexual, performed without sex, as is the case with clones, for example.
