This is Kawaguchi Hidetoshi. This is my humble answer to the question.
Certainly, we were born into a human world which is a world of confusion and suffering.
However, the difficulty of being born as this person is...
In Buddhism, there is an analogy called a “blind turtle driftwood,” and it is said that it is difficult for an old blind turtle living in the ocean to be born as a human to the extent that when it floats up to the surface of the sea once every 100 years, it just so happens to plunge its neck into a hole in a floating tree with a hole in it that flows there. Furthermore, it is said that being born into a world with Buddha's teachings and being able to learn and practice the Buddha's teachings is still difficult.
Also, along with Heaven and Shura, they are called “three good intentions” in the Rikudo Reincarnation, so there is no change in being lost and suffering, but it can be said that they are far better beings compared to Beast, Gakki, and Hell (Three Evils).
Furthermore, even with the three good intentions, in heaven and shura, it is difficult to successfully obtain “free time” (having 8 free time and 10 tools to move towards enlightenment and nirvana), so in reality, only people are the perfect opportunity to practice the Buddha's teachings, so they don't want to waste time as much as possible.
It is also conceivable that people were born to some extent due to a causal relationship (cause and condition) of good karma in past lives. We would like to somehow not miss this opportunity and continue to work hard on Buddhist practice in order to improve our mental qualities.
